Policy reporting tools indicate empty Internet Explorer Maintenance policy as winning


The Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022 (for a list of what's in scope, see the FAQ). The same IE11 apps and sites you use today can open in Microsoft Edge with Internet Explorer mode. Learn more here.

This article discusses information about manually deleting extensions in Group Policy after you delete the client's IEM settings.

After using the Internet Explorer Maintenance (IEM) context-menu option to Reset browser settings, a group policy object may be reported as the source of winning Internet Explorer Maintenance content even though the IEM settings have been removed.


The policy reporting tools identify the applicability of Internet Explorer Maintenance settings by the existence of their Client Side Extensions (CSE). The Reset browser settings option removes the IEM content but doesn't direct the policy editor to remove the extensions.


To work around this issue, administrators can leverage one of the two following options:

  1. Manually edit the affected group policy object and remove the Internet Explorer Maintenance gPCUserExtensionNames entries.

    • On Windows Server 2008 and later versions, you can modify the attributes using the following steps:

      • Open the Group Policy Editor, Select the affected group policy object.
      • Select the Details tab, Document the Unique ID.
    • Open the Active Directory Users and Computers snap-in.

      • Select the Domain Name > System > Policies.
      • Locate and Select the group policy object Unique ID obtained from above.
      • Right-click the policy object and choose Properties.
    • Click on the Attribute Editor tab

      • Locate and Select the entry for gPCUserExtensionNames.
      • Click Edit, Copy all of the entries listed.
      • Paste the entries into a new Notepad text file.
    • Remove the following client extensions from the Notepad content, if they exist:

      • {A2E30F80-D7DE-11d2-BBDE-00C04F86AE3B] // Internet Explorer Maintenance policy processing
      • {FC715823-C5FB-11D1-9EEF-00A0C90347FF} // Internet Explorer Maintenance Extension protocol
    • Copy the edited list from Notepad

      • Paste the updated extension list back into the gPCUserExtensionNames value field.
      • Click OK to exit the Attribute Editor.

      For environments prior to Windows Server 2008, use Active Directory Service Interfaces Editor(ADSI Edit) to remove the extensions manually.

  2. Create a new replacement group policy object, which contains all of the former non-IEM settings and unlink or disable the old policy.
