How to view all IE Trusted Sites when security settings are managed?

If the Security Zones for Internet Explorer are managed by my system administrator, the list of Trusted Sites is disabled and I cannot scroll through the list. Is there a way I can view the full list of Trusted Sites?

In the registry , perform a search for a URL that is known to be trusted. This should get you to the relevant key where you can see all of the others.

On my Windows 7 installation, the path appears to be HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMapKey , which is slightly different from this answer .

The key should contain several string values with a name indicating the URL and numeric data indicating the zone, one of the following by default.

• 0 = My Computer
• 1 = Local Intranet Zone
• 2 = Trusted sites Zone
• 3 = Internet Zone
• 4 = Restricted Sites Zone

• 8 Mine are all under HKEY_LOCAL_MACHINE –  Richard Collette Commented Sep 26, 2014 at 18:03

Depends upon your firm whether the list is under HKLM or HKCU. Here's a quick Powershell command to get the list

• 3 Remove the ".property" on the end of each line to see which zone the site is configured for: 1 = Local Intranet, 2 = Trusted Sites, 3 = Restricted Sites –  BateTech Commented Jul 10, 2019 at 12:25

From powershell:

• 1 Can you explain this answer/flesh it out a bit more for those who don't know PS as well? –  studiohack Commented Feb 10, 2015 at 16:13
• Start -> type gpedit.msc -> hit Enter
• navigate to Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page
• in the right-hand panel, double-click on the Site to Zone Assignment List option, then click Show...
• trusted sites are the ones with 2 in the Value column (1 = Intranet, 3 = Internet, 4 = Restricted)

If that doesn't work (that option is set to "Not Configured" or the list is empty), try the same, except instead of Computer Configuration, start with User Configuration.

• 3 Both of these settings are "Not Configured" and the lists are empty. –  JustinStolle Commented Apr 18, 2012 at 22:33

I came up with the following solution, I hope others will find it useful as well.

I have limited rights, only local, not enough to open and view GPEDIT on AD level.

So, what I did, and works, is to open a command prompt (as Admin) and run the command:

C:\WINDOWS\system32>GPResult /V /SCOPE Computer /H c:\temp\stuff.txt

Then perform a search e.g. for the "ZoneMapKey"

C:\WINDOWS\system32>find "ZoneMapKey" c:\temp\stuff.txt >> c:\temp\sites.txt

Keep in mind there are other keys that might require your attention, like the "approvedactivexinstalsites"...

You will have an output like:

KeyName: Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMapKey\https://www.wesayso.com

Clean it up (I use Excel, use the \ as seperator and be done with it) and you will have a great list.

• 4 I tried this but got an error "ERROR: Invalid Syntax. Options /U, /P, /R, /V, /Z cannot be specified along with /X, /H." –  Kidburla Commented Mar 18, 2015 at 15:39
• C:\WINDOWS\system32>GPResult /V /SCOPE COMPUTER >> c:\temp\stuff.txt generate the file for me. "COMPUTER" in caps per the help file. Use >> to write to file instead of /H –  MrChrister Commented Feb 4, 2019 at 22:58

This one works on my Windows 7 machine. It was set by my company's domain controller.

Here is an enhanced version of the script that translates the zone type number in the registry to its name as seen in the IE explorer settings dialog box.

Above we see how to gather the registry value names in a registry key and then get the data of each of those values. As each enter separates the value name and the value data with a comma, it could be further enhanced to output to a file with the csv extension and then opened in Excel. Many more possibilities if you want an actual report. But if just need to know what is the site list this will show most of them.

on windows 10 The URL are saved in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMapKey

to get the values you can brows to the above key or via PowerShell

My key was located here (in HKEY_LOCAL_MACHINE, not HKEY_CURRENT_USER)

I could right-click "ZoneMapKey" and choose "Export"

This .reg file can be opened in Notepad to view (and search) the text contents.

This PowerShell script provides a list from both registry keys if they are populated and uses the out-gridview cmdlet to provide a search capability using the out-gridview filter field.

Stick this in Powershell for a list of the trusted sites:

1 = Intranet zone – sites on your local network. 2 = Trusted Sites zone – sites that have been added to your trusted sites. 3 = Internet zone – sites that are on the Internet. 4 = Restricted Sites zone – sites that have been specifically added to your restricted sites.

Policy CSP - InternetExplorer

• 24 contributors

This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format> . For details, see Understanding ADMX-backed policies .

The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections .

This CSP contains some settings that are under development and only applicable for Windows Insider Preview builds . These settings are subject to change and may have dependencies on other features or services in preview.

AddSearchProvider

This policy setting allows you to add a specific list of search providers to the user's default list of search providers. Normally, search providers can be added from third-party toolbars or in Setup. The user can also add a search provider from the provider's website.

• If you enable this policy setting, the user can add and remove search providers, but only from the set of search providers specified in the list of policy keys for search providers (found under [HKCU or HKLM\Software\policies\Microsoft\Internet Explorer\SearchScopes]).

This list can be created from a custom administrative template file. For information about creating this custom administrative template file, see the Internet Explorer documentation on search providers.

• If you disable or don't configure this policy setting, the user can configure their list of search providers unless another policy setting restricts such configuration.

Description framework properties :

This is an ADMX-backed policy and requires SyncML format for configuration. For an example of SyncML format, refer to Enabling a policy .

ADMX mapping :

AllowActiveXFiltering

This policy setting controls the ActiveX Filtering feature for websites that are running ActiveX controls. The user can choose to turn off ActiveX Filtering for specific websites so that ActiveX controls can run properly.

If you enable this policy setting, ActiveX Filtering is enabled by default for the user. The user can't turn off ActiveX Filtering, although they may add per-site exceptions.

If you disable or don't configure this policy setting, ActiveX Filtering isn't enabled by default for the user. The user can turn ActiveX Filtering on or off.

AllowAddOnList

This policy setting allows you to manage a list of add-ons to be allowed or denied by Internet Explorer. Add-ons in this case are controls like ActiveX Controls, Toolbars, and Browser Helper Objects (BHOs) which are specifically written to extend or enhance the functionality of the browser or web pages.

This list can be used with the 'Deny all add-ons unless specifically allowed in the Add-on List' policy setting, which defines whether add-ons not listed here are assumed to be denied.

• If you enable this policy setting, you can enter a list of add-ons to be allowed or denied by Internet Explorer. For each entry that you add to the list, enter the following information:

Name of the Value - the CLSID (class identifier) for the add-on you wish to add to the list. The CLSID should be in brackets for example, '{000000000-0000-0000-0000-0000000000000}'. The CLSID for an add-on can be obtained by reading the OBJECT tag from a Web page on which the add-on is referenced.

Value - A number indicating whether Internet Explorer should deny or allow the add-on to be loaded. To specify that an add-on should be denied enter a 0 (zero) into this field. To specify that an add-on should be allowed, enter a 1 (one) into this field. To specify that an add-on should be allowed and also permit the user to manage the add-on through Add-on Manager, enter a 2 (two) into this field.

• If you disable this policy setting, the list is deleted. The 'Deny all add-ons unless specifically allowed in the Add-on List' policy setting will still determine whether add-ons not in this list are assumed to be denied.

AllowAutoComplete

This AutoComplete feature can remember and suggest User names and passwords on Forms.

If you enable this setting, the user can't change "User name and passwords on forms" or "prompt me to save passwords". The Auto Complete feature for User names and passwords on Forms will be turned on. You have to decide whether to select "prompt me to save passwords".

If you disable this setting the user can't change "User name and passwords on forms" or "prompt me to save passwords". The Auto Complete feature for User names and passwords on Forms is turned off. The user also can't opt to be prompted to save passwords.

If you don't configure this setting, the user has the freedom of turning on Auto complete for User name and passwords on forms and the option of prompting to save passwords. To display this option, the users open the Internet Options dialog box, click the Contents Tab and click the Settings button.

AllowCertificateAddressMismatchWarning

This policy setting allows you to turn on the certificate address mismatch security warning. When this policy setting is turned on, the user is warned when visiting Secure HTTP (HTTPS) websites that present certificates issued for a different website address. This warning helps prevent spoofing attacks.

If you enable this policy setting, the certificate address mismatch warning always appears.

If you disable or don't configure this policy setting, the user can choose whether the certificate address mismatch warning appears (by using the Advanced page in the Internet Control panel).

AllowDeletingBrowsingHistoryOnExit

This policy setting allows the automatic deletion of specified items when the last browser window closes. The preferences selected in the Delete Browsing History dialog box (such as deleting temporary Internet files, cookies, history, form data, and passwords) are applied, and those items are deleted.

If you enable this policy setting, deleting browsing history on exit's turned on.

If you disable this policy setting, deleting browsing history on exit's turned off.

If you don't configure this policy setting, it can be configured on the General tab in Internet Options.

If the "Prevent access to Delete Browsing History" policy setting is enabled, this policy setting has no effect.

AllowEnhancedProtectedMode

Enhanced Protected Mode provides additional protection against malicious websites by using 64-bit processes on 64-bit versions of Windows. For computers running at least Windows 8, Enhanced Protected Mode also limits the locations Internet Explorer can read from in the registry and the file system.

If you enable this policy setting, Enhanced Protected Mode will be turned on. Any zone that has Protected Mode enabled will use Enhanced Protected Mode. Users won't be able to disable Enhanced Protected Mode.

If you disable this policy setting, Enhanced Protected Mode will be turned off. Any zone that has Protected Mode enabled will use the version of Protected Mode introduced in Internet Explorer 7 for Windows Vista.

If you don't configure this policy, users will be able to turn on or turn off Enhanced Protected Mode on the Advanced tab of the Internet Options dialog.

AllowEnhancedSuggestionsInAddressBar

This policy setting allows Internet Explorer to provide enhanced suggestions as the user types in the Address bar. To provide enhanced suggestions, the user's keystrokes are sent to Microsoft through Microsoft services.

If you enable this policy setting, users receive enhanced suggestions while typing in the Address bar. In addition, users won't be able to change the Suggestions setting on the Settings charm.

If you disable this policy setting, users won't receive enhanced suggestions while typing in the Address bar. In addition, users won't be able to change the Suggestions setting on the Settings charm.

If you don't configure this policy setting, users can change the Suggestions setting on the Settings charm.

AllowEnterpriseModeFromToolsMenu

This policy setting lets you decide whether users can turn on Enterprise Mode for websites with compatibility issues. Optionally, this policy also lets you specify where to get reports (through post messages) about the websites for which users turn on Enterprise Mode using the Tools menu.

If you turn this setting on, users can see and use the Enterprise Mode option from the Tools menu. If you turn this setting on, but don't specify a report location, Enterprise Mode will still be available to your users, but you won't get any reports.

If you disable or don't configure this policy setting, the menu option won't appear and users won't be able to run websites in Enterprise Mode.

AllowEnterpriseModeSiteList

This policy setting lets you specify where to find the list of websites you want opened using Enterprise Mode IE, instead of Standard mode, because of compatibility issues. Users can't edit this list.

If you enable this policy setting, Internet Explorer downloads the website list from your location (HKCU or HKLM\Software\policies\Microsoft\Internet Explorer\Main\EnterpriseMode), opening all listed websites using Enterprise Mode IE.

If you disable or don't configure this policy setting, Internet Explorer opens all websites using Standards mode.

AllowFallbackToSSL3

This policy setting allows you to block an insecure fallback to SSL 3.0. When this policy is enabled, Internet Explorer will attempt to connect to sites using SSL 3.0 or below when TLS 1.0 or greater fails.

We recommend that you don't allow insecure fallback in order to prevent a man-in-the-middle attack.

This policy doesn't affect which security protocols are enabled.

If you disable this policy, system defaults will be used.

AllowInternetExplorer7PolicyList

This policy setting allows you to add specific sites that must be viewed in Internet Explorer 7 Compatibility View.

If you enable this policy setting, the user can add and remove sites from the list, but the user can't remove the entries that you specify.

If you disable or don't configure this policy setting, the user can add and remove sites from the list.

AllowInternetExplorerStandardsMode

This policy setting controls how Internet Explorer displays local intranet content. Intranet content is defined as any webpage that belongs to the local intranet security zone.

If you enable this policy setting, Internet Explorer uses the current user agent string for local intranet content. Additionally, all local intranet Standards Mode pages appear in the Standards Mode available with the latest version of Internet Explorer. The user can't change this behavior through the Compatibility View Settings dialog box.

If you disable this policy setting, Internet Explorer uses an Internet Explorer 7 user agent string (with an additional string appended) for local intranet content. Additionally, all local intranet Standards Mode pages appear in Internet Explorer 7 Standards Mode. The user can't change this behavior through the Compatibility View Settings dialog box.

If you don't configure this policy setting, Internet Explorer uses an Internet Explorer 7 user agent string (with an additional string appended) for local intranet content. Additionally, all local intranet Standards Mode pages appear in Internet Explorer 7 Standards Mode. This option results in the greatest compatibility with existing webpages, but newer content written to common Internet standards may be displayed incorrectly. This option matches the default behavior of Internet Explorer.

AllowInternetZoneTemplate

This template policy setting allows you to configure policy settings in this zone consistent with a selected security level, for example, Low, Medium Low, Medium, or High.

If you enable this template policy setting and select a security level, all values for individual settings in the zone will be overwritten by the standard template defaults.

If you disable this template policy setting, no security level is configured.

If you don't configure this template policy setting, no security level is configured.

Note. Local Machine Zone Lockdown Security and Network Protocol Lockdown operate by comparing the settings in the active URL's zone against those in the Locked-Down equivalent zone. If you select a security level for any zone (including selecting no security), the same change should be made to the Locked-Down equivalent.

Note. It's recommended to configure template policy settings in one Group Policy object (GPO) and configure any related individual policy settings in a separate GPO. You can then use Group Policy management features (for example, precedence, inheritance, or enforce) to apply individual settings to specific targets.

AllowIntranetZoneTemplate

Allowlegacyurlfields.

This policy setting allows the use of some disabled functionality, such as WorkingDirectory field or pluggable protocol handling, in Internet Shortcut files.

If you enable this policy, disabled functionality for Internet Shortcut files will be re-enabled.

If you disable, or don't configure this policy, some functionality for Internet Shortcut files, such as WorkingDirectory field or pluggable protocol handling, will be disabled.

AllowLocalMachineZoneTemplate

Allowlockeddowninternetzonetemplate, allowlockeddownintranetzonetemplate, allowlockeddownlocalmachinezonetemplate, allowlockeddownrestrictedsiteszonetemplate, allowonewordentry.

This policy allows the user to go directly to an intranet site for a one-word entry in the Address bar.

If you enable this policy setting, Internet Explorer goes directly to an intranet site for a one-word entry in the Address bar, if it's available.

If you disable or don't configure this policy setting, Internet Explorer doesn't go directly to an intranet site for a one-word entry in the Address bar.

AllowSaveTargetAsInIEMode

This policy setting allows admins to enable "Save Target As" context menu in Internet Explorer mode.

If you enable this policy, "Save Target As" will show up in the Internet Explorer mode context menu and work the same as Internet Explorer.

If you disable or don't configure this policy setting, "Save Target As" won't show up in the Internet Explorer mode context menu.

For more information, see https://go.microsoft.com/fwlink/?linkid=2102115

AllowSiteToZoneAssignmentList

This policy setting allows you to manage a list of sites that you want to associate with a particular security zone. These zone numbers have associated security settings that apply to all of the sites in the zone.

Internet Explorer has 4 security zones, numbered 1-4, and these are used by this policy setting to associate sites to zones. They are: (1) Intranet zone, (2) Trusted Sites zone, (3) Internet zone, and (4) Restricted Sites zone. Security settings can be set for each of these zones through other policy settings, and their default settings are: Trusted Sites zone (Low template), Intranet zone (Medium-Low template), Internet zone (Medium template), and Restricted Sites zone (High template). (The Local Machine zone and its locked down equivalent have special security settings that protect your local computer).

• If you enable this policy setting, you can enter a list of sites and their related zone numbers. The association of a site with a zone will ensure that the security settings for the specified zone are applied to the site. For each entry that you add to the list, enter the following information:

Valuename - A host for an intranet site, or a fully qualified domain name for other sites. The valuename may also include a specific protocol. For example, if you enter https://www.contoso.com as the valuename, other protocols aren't affected. If you enter just www.contoso.com , then all protocols are affected for that site, including http, https, ftp, and so on. The site may also be expressed as an IP address (e.g., 127.0.0.1) or range (e.g., 127.0.0.1-10). To avoid creating conflicting policies, don't include additional characters after the domain such as trailing slashes or URL path. For example, policy settings for www.contoso.com and www.contoso.com/mail would be treated as the same policy setting by Internet Explorer, and would therefore be in conflict.

Value - A number indicating the zone with which this site should be associated for security settings. The Internet Explorer zones described above are 1-4.

• If you disable or don't configure this policy, users may choose their own site-to-zone assignments.

This policy is a list that contains the site and index value.

The list is a set of pairs of strings. Each string is separated by F000. Each pair of strings is stored as a registry name and value. The registry name is the site and the value is an index. The index has to be sequential. See an example below.

Value and index pairs in the SyncML example:

• https://adfs.contoso.org 1
• https://microsoft.com 2

AllowsLockedDownTrustedSitesZoneTemplate

Allowsoftwarewhensignatureisinvalid.

This policy setting allows you to manage whether software, such as ActiveX controls and file downloads, can be installed or run by the user even though the signature is invalid. An invalid signature might indicate that someone has tampered with the file.

If you enable this policy setting, users will be prompted to install or run files with an invalid signature.

If you disable this policy setting, users can't run or install files with an invalid signature.

If you don't configure this policy, users can choose to run or install files with an invalid signature.

AllowsRestrictedSitesZoneTemplate

Allowsuggestedsites.

This policy setting controls the Suggested Sites feature, which recommends websites based on the user's browsing activity. Suggested Sites reports a user's browsing history to Microsoft to suggest sites that the user might want to visit.

If you enable this policy setting, the user isn't prompted to enable Suggested Sites. The user's browsing history is sent to Microsoft to produce suggestions.

If you disable this policy setting, the entry points and functionality associated with this feature are turned off.

If you don't configure this policy setting, the user can turn on and turn off the Suggested Sites feature.

AllowTrustedSitesZoneTemplate

Checkservercertificaterevocation.

This policy setting allows you to manage whether Internet Explorer will check revocation status of servers' certificates. Certificates are revoked when they've been compromised or are no longer valid, and this option protects users from submitting confidential data to a site that may be fraudulent or not secure.

If you enable this policy setting, Internet Explorer will check to see if server certificates have been revoked.

If you disable this policy setting, Internet Explorer won't check server certificates to see if they've been revoked.

If you don't configure this policy setting, Internet Explorer won't check server certificates to see if they've been revoked.

CheckSignaturesOnDownloadedPrograms

This policy setting allows you to manage whether Internet Explorer checks for digital signatures (which identifies the publisher of signed software and verifies it hasn't been modified or tampered with) on user computers before downloading executable programs.

If you enable this policy setting, Internet Explorer will check the digital signatures of executable programs and display their identities before downloading them to user computers.

If you disable this policy setting, Internet Explorer won't check the digital signatures of executable programs or display their identities before downloading them to user computers.

If you don't configure this policy, Internet Explorer won't check the digital signatures of executable programs or display their identities before downloading them to user computers.

ConfigureEdgeRedirectChannel

Enables you to configure up to three versions of Microsoft Edge to open a redirected site (in order of preference). Use this policy if your environment is configured to redirect sites from Internet Explorer 11 to Microsoft Edge. If any of the chosen versions aren't installed on the device, that preference will be bypassed.

If both the Windows Update for the next version of Microsoft Edge* and Microsoft Edge Stable channel are installed, the following behaviors occur:

If you disable or don't configure this policy, Microsoft Edge Stable channel is used. This is the default behavior.

If you enable this policy, you can configure redirected sites to open in up to three of the following channels where:

1 = Microsoft Edge Stable 2 = Microsoft Edge Beta version 77 or later 3 = Microsoft Edge Dev version 77 or later 4 = Microsoft Edge Canary version 77 or later.

If the Windows Update for the next version of Microsoft Edge* or Microsoft Edge Stable channel aren't installed, the following behaviors occur:

If you disable or don't configure this policy, Microsoft Edge version 45 or earlier is automatically used. This is the default behavior.

0 = Microsoft Edge version 45 or earlier 1 = Microsoft Edge Stable 2 = Microsoft Edge Beta version 77 or later 3 = Microsoft Edge Dev version 77 or later 4 = Microsoft Edge Canary version 77 or later.

• For more information about the Windows update for the next version of Microsoft Edge including how to disable it, see< https://go.microsoft.com/fwlink/?linkid=2102115> . This update applies only to Windows 10 version 1709 and higher.

ConsistentMimeHandlingInternetExplorerProcesses

Internet Explorer uses Multipurpose Internet Mail Extensions (MIME) data to determine file handling procedures for files received through a Web server.

This policy setting determines whether Internet Explorer requires that all file-type information provided by Web servers be consistent. For example, if the MIME type of a file is text/plain but the MIME sniff indicates that the file is really an executable file, Internet Explorer renames the file by saving it in the Internet Explorer cache and changing its extension.

If you enable this policy setting, Internet Explorer requires consistent MIME data for all received files.

If you disable this policy setting, Internet Explorer won't require consistent MIME data for all received files.

If you don't configure this policy setting, Internet Explorer requires consistent MIME data for all received files.

DisableActiveXVersionListAutoDownload

This setting determines whether IE automatically downloads updated versions of Microsoft's VersionList. XML. IE uses this file to determine whether an ActiveX control should be stopped from loading.

If you enable this setting, IE stops downloading updated versions of VersionList. XML. Turning off this automatic download breaks the out-of-date ActiveX control blocking feature by not letting the version list update with newly outdated controls, potentially compromising the security of your computer.

If you disable or don't configure this setting, IE continues to download updated versions of VersionList. XML.

For more information, see "Out-of-date ActiveX control blocking" in the Internet Explorer TechNet library.

DisableBypassOfSmartScreenWarnings

This policy setting determines whether the user can bypass warnings from SmartScreen Filter. SmartScreen Filter prevents the user from browsing to or downloading from sites that are known to host malicious content. SmartScreen Filter also prevents the execution of files that are known to be malicious.

If you enable this policy setting, SmartScreen Filter warnings block the user.

If you disable or don't configure this policy setting, the user can bypass SmartScreen Filter warnings.

DisableBypassOfSmartScreenWarningsAboutUncommonFiles

This policy setting determines whether the user can bypass warnings from SmartScreen Filter. SmartScreen Filter warns the user about executable files that Internet Explorer users don't commonly download from the Internet.

DisableCompatView

This policy setting controls the Compatibility View feature, which allows the user to fix website display problems that he or she may encounter while browsing.

If you enable this policy setting, the user can't use the Compatibility View button or manage the Compatibility View sites list.

If you disable or don't configure this policy setting, the user can use the Compatibility View button and manage the Compatibility View sites list.

DisableConfiguringHistory

This setting specifies the number of days that Internet Explorer tracks views of pages in the History List. To access the Temporary Internet Files and History Settings dialog box, from the Menu bar, on the Tools menu, click Internet Options, click the General tab, and then click Settings under Browsing history.

If you enable this policy setting, a user can't set the number of days that Internet Explorer tracks views of the pages in the History List. You must specify the number of days that Internet Explorer tracks views of pages in the History List. Users can't delete browsing history.

If you disable or don't configure this policy setting, a user can set the number of days that Internet Explorer tracks views of pages in the History list. Users can delete browsing history.

DisableCrashDetection

This policy setting allows you to manage the crash detection feature of add-on Management.

If you enable this policy setting, a crash in Internet Explorer will exhibit behavior found in Windows XP Professional Service Pack 1 and earlier, namely to invoke Windows Error Reporting. All policy settings for Windows Error Reporting continue to apply.

If you disable or don't configure this policy setting, the crash detection feature for add-on management will be functional.

DisableCustomerExperienceImprovementProgramParticipation

This policy setting prevents the user from participating in the Customer Experience Improvement Program (CEIP).

If you enable this policy setting, the user can't participate in the CEIP, and the Customer Feedback Options command doesn't appear on the Help menu.

If you disable this policy setting, the user must participate in the CEIP, and the Customer Feedback Options command doesn't appear on the Help menu.

If you don't configure this policy setting, the user can choose to participate in the CEIP.

DisableDeletingUserVisitedWebsites

This policy setting prevents the user from deleting the history of websites that he or she has visited. This feature is available in the Delete Browsing History dialog box.

If you enable this policy setting, websites that the user has visited are preserved when he or she clicks Delete.

If you disable this policy setting, websites that the user has visited are deleted when he or she clicks Delete.

If you don't configure this policy setting, the user can choose whether to delete or preserve visited websites when he or she clicks Delete.

If the "Prevent access to Delete Browsing History" policy setting is enabled, this policy setting is enabled by default.

DisableEnclosureDownloading

This policy setting prevents the user from having enclosures (file attachments) downloaded from a feed to the user's computer.

If you enable this policy setting, the user can't set the Feed Sync Engine to download an enclosure through the Feed property page. A developer can't change the download setting through the Feed APIs.

If you disable or don't configure this policy setting, the user can set the Feed Sync Engine to download an enclosure through the Feed property page. A developer can change the download setting through the Feed APIs.

DisableEncryptionSupport

This policy setting allows you to turn off support for Transport Layer Security (TLS) 1.0, TLS 1.1, TLS 1.2, Secure Sockets Layer (SSL) 2.0, or SSL 3.0 in the browser. TLS and SSL are protocols that help protect communication between the browser and the target server. When the browser attempts to set up a protected communication with the target server, the browser and server negotiate which protocol and version to use. The browser and server attempt to match each other's list of supported protocols and versions, and they select the most preferred match.

If you enable this policy setting, the browser negotiates or doesn't negotiate an encryption tunnel by using the encryption methods that you select from the drop-down list.

If you disable or don't configure this policy setting, the user can select which encryption method the browser supports.

SSL 2.0 is off by default and is no longer supported starting with Windows 10 Version 1607. SSL 2.0 is an outdated security protocol, and enabling SSL 2.0 impairs the performance and functionality of TLS 1.0.

DoNotAllowActiveXControlsInProtectedMode

This policy setting prevents ActiveX controls from running in Protected Mode when Enhanced Protected Mode is enabled. When a user has an ActiveX control installed that isn't compatible with Enhanced Protected Mode and a website attempts to load the control, Internet Explorer notifies the user and gives the option to run the website in regular Protected Mode. This policy setting disables this notification and forces all websites to run in Enhanced Protected Mode.

When Enhanced Protected Mode is enabled, and a user encounters a website that attempts to load an ActiveX control that isn't compatible with Enhanced Protected Mode, Internet Explorer notifies the user and gives the option to disable Enhanced Protected Mode for that particular website.

If you enable this policy setting, Internet Explorer won't give the user the option to disable Enhanced Protected Mode. All Protected Mode websites will run in Enhanced Protected Mode.

If you disable or don't configure this policy setting, Internet Explorer notifies users and provides an option to run websites with incompatible ActiveX controls in regular Protected Mode. This is the default behavior.

DoNotAllowUsersToAddSites

Prevents users from adding or removing sites from security zones. A security zone is a group of Web sites with the same security level.

If you enable this policy, the site management settings for security zones are disabled. (To see the site management settings for security zones, in the Internet Options dialog box, click the Security tab, and then click the Sites button).

If you disable this policy or don't configure it, users can add Web sites to or remove sites from the Trusted Sites and Restricted Sites zones, and alter settings for the Local Intranet zone.

This policy prevents users from changing site management settings for security zones established by the administrator.

The "Disable the Security page" policy (located in \User Configuration\Administrative Templates\Windows Components\Internet Explorer\Internet Control Panel), which removes the Security tab from the interface, takes precedence over this policy. If it's enabled, this policy is ignored.

Also, see the "Security zones: Use only machine settings" policy.

Adding Sites to Internet Security Zones Using Group Policy

Sometimes it is useful to leverage the power of Group Policy in Active Directory to add sites to certain security zones in Internet Explorer.  This can save the network admin the trouble of managing the security zone lists for each computer (or user) separately.  In the following example, each user on the network needs to have a specific site added to the Trusted Sites list.

This tutorial assumes that group policy is in good working order on the domain and that all client users and computers can access the directory.

• Open the Group Policy Management MMC console.
• Right-click the organization unit (OU) that the policy should apply to, taking special care to consider whether the policy should apply to computers or users on this particular network.
• Select “Create and Link a GPO Here…” to create a new group policy object.
• In the “New GPO” window, enter a good, descriptive name for this new policy and click “OK”.   (ex.  “Trusted Sites Zone – Users” or something even more descriptive)
• Locate the newly created GPO in the left-side navigation pane, right-click it and select “Edit…”
• Expand “Administrative Templates” under either “Computer Configuration” or “User Configuration” depending on which type of OU the new policy was linked to in step 2.
• The path to the settings that this example will be using is: Administrative Templates -- Windows Components -- Internet Explorer -- Internet Control Panel -- Security Page
• In the right-hand pane, double-click “Site to Zone Assignment List”.
• Enable the policy and click the “Show…” button next to “Enter the zone assignments here.”  This will pop up the “Show Contents” window.
• Click the “Add…” button.  This will pop up the “Add Item” window.
• In the first box, labeled “Enter the name of the item to be added:”, enter the URL to the site.   (ex.  https://secure.ourimportantwebapp.com) .  Keep in mind that wildcards can be used.   (ex.  https://*.ourimportantdomain.com) .  Leave off any trailing slashes or sub-folders unless that type of specific control is called for.
• 1 – Intranet Zone
• 2 – Trusted Sites Zone
• 3 – Internet Zone
• 4 – Restricted Sites Zone
• Once the zone assignment has been entered, click “OK”.  This will once again show the “Show Contents” window and the new entry should be present.
• Click “OK” and “OK” again to get back to the Group Policy Management Console.

The new policy will take effect at the next group policy refresh interval, which is usually 15 minutes.  To test immediately, run a gpupdate /force on a user/computer that falls into the scope of the new policy and go to “Tools -> Internet Options -> Security -> Trusted Sites -> Sites”.  The site(s) added should be in the list.  If the sites do not show up, check the event logs for any group policy processing errors.

How to configuring IE Site Zone mapping using group policy without locking out the user

Put simply we are going to setup the IE Zone registry keys manually using Group Policy Preferences…

However it’s a little complicated as the URL that is in the Site to Zone mapping is actually stored as the name of the key. Finally the protocol is the registry value with a number that assigns it to the corresponding zone. In the example we use we will first look at the currently site that the users has setup in the trusted site list ( www.bing.com ). As you can see below the zone is store at HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains then the domain is stored as a key “Bing.com” then “www”. Within the “www” key the protocol (http and/or https) is the value name with the value representing what zone it should be a member.

Note: We are just using bing.com as an example as you would never add at search engine as a trusted site.

Now we will add the additional site www.google.com.au also to the trusted sites list using group policy.

Step 1 . Edit a Group Policy that is targeted to the users that you want the IE Zones applied.

Step 2. Create a new Group Policy Preferences Registry Extension then select the “HKEY_CURRENT_USERS” Hive and then type “Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\google.com.au\www” in the Key path. Then enter the Value name of “HTTP” and selected the Value Type as “REG_DWORD” and set the value data as “00000002”.

And you’re Done…

TIP: For your reference the values and their corresponding Zones are listed below in the table.

As you can see below the IE zone will push out to your users and it will be added to the trusted zone list, while still allowing them to add and remove other zones from the list.

TIP: As always the native group policy settings will take precedence over Group Policy Preferences therefore if you have the “Site to Zone Assignment List” setting configured as well this will override (not merge) the above settings (See image below).

I worked this one out on my own a few years back, Should have written a blog / guide back then! I’d be a millionnaire!!

But still – this is a great way to allow the users to add their own trusts, of on site to fix a broken site without returning to GPO Editor just for a single user!

• Pingback: Security Tip: Block Internet Explorer invocation of Java with Group Policy

I wasn’t able to get this to work. I tried it on both User and Computer settings. There was no sub folder under ‘hotmail.com’. The domain I’m trying to remove.

I’m unable to get this to work. Even the group policy results test shows it is successful, but it never shows up in the IE Internet settings. I’ve added a REG entry to also “uncheck” the require https: and that doesn’t show up either. I’ve test on both WinXP with IE8 and Win7 with IE9. Same results. I’ve looked at the registry and see nothing added. Plus, there are no errors in the event log.

Strange behavior.

I just troubleshooted with the same problem that it was not working with no error message to troubleshoot anywhere.

SOLUTION: I fired up regedit and navigated to “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\” There I saw the site I wanted to add as a sub-key to “ZoneMap” and not as a subkey to “Domains” as it is supposed to be. The “Domains” subkey was empty. I deleted the site from “ZoneMap” and then did a gpupdate. When I then refreshed regedit the site was created no the correct location and everything was working. 🙂

Thanks for the info, but this isn’t my experience at all.

I’ve checked the registry for this same error and see nothing. I’ve even searched the entire registry for the domain name, and it finds nothing…

I’ve got a computer policy that is applied to the OU where the computer lives. All items in the policy are updating successfully, except for the registry entries. I’ve run the group policy results and see no errors. I’ve even created the policy by using the registry wizard and importing the items from my local registry. When I check the local registry on my test machines, I see nothing change. If I add the entries via IE, then they show up in the correct places. I’m stumped why this isn’t working…

Tough one. I often had typos in the GP preferences mess things up for me in the past, also the correct amount of \ signs in the key path is important. Personally I have never used it in computer policy, but I’ve always used user policy, perhaps that is worth a try? Also I always use “Replace” and not “update” in the GP Preference.

What do you mean by, “the correct amount of signs in the key path”? What is a sign?

I had the same thought about user policy yesterday and tried that as well. No luck. I haven’t tried the “Replace” option. I’ll test that next.

A bit clumsy explained, sorry about that. But I meant where you put the (slash) \ in the path. “Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\*.contoso.com” is the correct path, but if you write “\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\*.contoso.com” or “Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\*.contoso.com\” then it will fail.

Not sure why but I can’t make this work at all. The GPP does not write the reg entries at all. I tried changing the action to create and also update, but no difference. Any suggestions?

well John, you don’t really tell me much of your setup so there is not much for me to go on here. But in general my checklist would be something like this:

1. It’s a GPP setting under the user (not computer) and it writes to the HKCU hive? 2. Use “replace” 3. Trippe-check that the path is written correctly. For example: “Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\*.contoso.com” 4. Use “gpresult -r” on the client computer to check that the user gets the GPP 5. If the user gets the GPP, check the application log on the computer. If a GPP fails you will see it in the application log at the time the user logs in and it usually tells you why.

That’s my suggestions at the moment.

You nailed the problem – I was using a computer policy, not a user policy. As soon as a rebuilt it as a user policy, everything fell into place perfectly. Thanks for posting this, it was a huge timesaver!

You’re welcome, I’m glad I could help. 🙂

Excellent post. I was just trying to figure out the exact registry keys to modify when I found this page. Nice work !

For the same case.. My user wants to add site to their trusted site list.. Please help…

Mahfuj: I’m not sure what you mean. If you use GPP to configure the IE zones then the users are allowed to add sites to them. Do you want ot prevernt them from adding sites to the trusted site list? Or do you want to allow them to add sites to the trusted site list?

Yes.. I want my user will add sites to trusted site list….. But “Add this website to the zone” field and “Add” button is gray out.. for all users.

Yes.. I want to allow my users to add sites to trusted site list….. But “Add this website to the zone” field and “Add” button is gray out.. for all users.

This means you have the administrative template still configured for the user so it will prevent them from editing their zone list. You have to be sure that you ONLY configure IE site zones via Group Policy Preferences…

I agree with Alan, it is most likely another GPO that contains settings for the IE zones, either in computer or user settings.

Thanks… I’ve figureout the issue.. Site to zone assignments list should be Not Configured for both Computer and user configuration settings….

You have a typo in the third paragraph that starts with “Hoever it’s a little complicted. Typo: “As you can see below the zone is store at HKCU\Software\Microsoft\CurrentVersion\Internet Settings\ZoneMap\Domains…” should be “As you can see below the zone is store at HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains…” The “Windows” part of the path is missing 😉

@KJS thanks.. I have corrected…

What versions of IE does this method support?

I have not tested it… but I think will work with all versions.

I am really loathing the decision by MS to go down the GPP route without replacing existing functionality with something equally simple. With this Zone mapping and the amount of work with getting favourites working it is a nightmare trying to replace existing simple easily updated GPOs with GPPs, I am not looking forward to doing it for Office.

Helpful. Thanks

Worked perfectly; delivering the following record helped the annoying windows security prompts for executing VBS/HTA files off network shares: file://privateDomainName.FQDN 1 file://privateDomainName 1

Many thanks,

My spouse and I absolutely love your blog and find a lot of your post’s to be exactly what I’m looking for. Would you offer guest writers to write content for you personally? I wouldn’t mind producing a post or elaborating on some of the subjects you write concerning here. Again, awesome weblog!

That brings us to quite possibly the most intriguing match-up to that point of the season when Oregon comes to Rice-Eccles. Alabama will try to rebound from their loss to the Sooners and rank fourth in the Sporting News college football preseason rankings. Ole Miss and Mississippi State moving the Egg Bowl away from Jackson, Miss.

What’s up, always i used to check web site posts here in the early hours in the morning, because i like to find out more and more.

Alan, great post. I’m having this issue my question is would this solution work for widows 7?

Yes it will

Very helpful posting, many thanks.

Has anyone had trouble getting this to work with Windows XP? It works well with all my Win& PC’s but is hit and miss on the XP.

Had a similar Issue, however a little different. This article may help you… http://www.grishbi.com/2015/03/unable-to-change-ie-zone-security-settings/

Excellent work Alan.

I know it is mentioned, but I would re-emphasize http or https as required.

As Per-Torben Sørensen suggested, use Replace. I’ve had issues with update instead of replace so I always use replace. It seems update doesn’t add something if it is missing, but replace does.

Remember rsop.msc is your friend. It doesn’t show the registry changes, but does show if an additional policy is applied that overrides the registry settings. With these specific settings, you can do a C:\>gpupdate /force, close and re-open the browser or re-run rsop.msc to see if the changes took place. All without logging out and back in, or rebooting.

Best, David

Much appreciated. Need to retain as much of the admin aspects for people doing programming while still giving them the tools needed for internal sites.

I am able to get the GP to work fine, however the site I am adding still doesn’t come up under the Intranet Zone as I have set. I am trying to add the internal IP of the site – 192.0.0.25. When I add this manually in IE, it works fine. When done through GP, it shows in IE under the Intranet zone, but doesn’t get treated like an intranet zone (File > properties, shows it as Internet). Is there a way to use the IP address instead of the domain name?

We needed to add a list of no less than 10 sites to the trusted list. Rather than doing it individually as you have shown, I exported the “Domains” key to a shared drive and then created a logon script that copies it to the local machine and then imports it to the registry. Now, whenever we need to add more trusted sites, I can just update the reg key in the shared location.

Question on using Wild Cards in the URL. I just found your post yesterday and am very excited about testing out using preferences in place of policies for our list of trusted sites.

I have several URLs that I am using wildcards in. If I enter the wildcard in the key path (Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\*.contoso.com) I end up with this listed in trusted sites in IE: http://*.contoso.com .

Will this function properly for all domains that add a prefix to .contoso.com? Also, is there anyway to use a wildcard to it would work with either http or https sites? We have several of those.

Excellent article…..working for me. One thing I want to mention that If you want to add just e.g., http://google.com it is working fine. but if you want to add http://google.com/xyz then you should add google.com/xyz after \Domains\ e.g. Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\google.com/xyz

Thanks for posting.

Is this applicable for HKLM registry location via GPP?

Since we need to implement for machine level.

Brilliant, thanks for this blog, works like a treat. thanks for your effort putting this up 5 years later and people are still coming across these things 🙂

Group Policy Management about:security_mmc

In Group Policy Management, when I click on an existing GPO, I get an Internet Explorer Enhanced Security Configuration messaged that "about:security_mmc.exe" is not a trusted site.

It happens every time I click a different GPO. I read to add this to the trusted site list, which I did. I confirmed it is in the policy when I do gpresult.

But I'm still getting this message. Anything else I need to do so this doesn't keep popping up?

• active-directory
• group-policy

• That usually means the host has Internet Explorer protected mode enabled. –  Greg Askew Commented Jul 2, 2021 at 22:27
• @GregAskew There should be a way to have protected mode enabled and not have this pop up. In an environment where I was not involved the the Domain level configuration, I do not get this problem on servers that have protected mode enabled. –  user3271408 Commented Jul 7, 2021 at 20:04

As someone who has just spent a half a day researching and doing things like monitoring processes and the registry wondering why the Site to Zone Assignment List GPO was not applying to servers with IE Enhanced Security Configuration on, I may have found a solution. We always use the Computer Settings part of the GPO to force it on the entire computer/server (we do not use the User Settings unless it needs to be applied to specific groups of users. In this case, this policy in our organization needs to apply to devices.)

We don't turn off the IE Enhanced Security Configuration (IE ESC) on any of our servers and I was determined to find a solution.

After monitoring the registry/process explorer and wading through that, I discovered the problem.

When you set the Site to Zone Assignment List , it writes this information in the registry to:

If IE ESC is off, when you go to:

you will see the sites listed there.

If IE ESC is on, the same location in the Control Panel above yields a blank list, as another response pointed out.

The problem is when IE ESC is on, I found that it does not use the registry location above. It reads from this location instead:

(The registry key is prefixed with Esc .) There appears to be no way to fix this in policy - however, this problem can simply be solved by manually writing a registry entry or, in the case of policies, I added an entry under:

that looks like this:

With this added entry to our exiting policy with the settings in Site to Zone Assignment List , I have pushed this out to all of our servers, and now with IE ESC mode on, it shows up under the Sites list under Trusted Sites as it should - and it behaves how it should.

No more warnings when working on/viewing policies!

• Thank you, Danomac. I've implemented this via GPO in three OUs and it worked for the computers in two of them. So there appears to be another dependent setting that I have set in the two working OUs but not on the one non-working. If I discover the dependent setting, I'll add that as well. Thanks again. –  user3271408 Commented Apr 17 at 17:09

As soon as you use Site to Zone Assignment List in a (computer) GPO: everything else is blocked including the built-in ones, and you cannot see the list.

I have to do some test to pinpoint exactly where this comes from but long story short: prefer using (user-side) Zone mapping GPO that is simply adding registry entries.

JJStellato's answer from this social TechNet post helped me figure it out. As well as the last reply from Alan Burchill.

Microsoft - IE security zones registry entries for advanced users

Microsoft - IE Enhanced Security Configuration

When you say you added it to trusted sites, did you add it within the GPO only or manually on the server itself? If you added it via GPO, it may take some time to replicate to that server.

You can run rsop.msc to check your applied group policies.

You can check IE trusted sites on the local server as well( settings )

• I added it via GPO more than a week ago. My Internet Option settings are grayed out, so I cannot check there. When I run rsop.msc, I do see it listed there as I expect it would. –  user3271408 Commented Jul 2, 2021 at 18:48
