Windows cannot read the history of GPOs from the registry. Continuing Group Policy Processing.

Details
Product: Windows Operating System
Event ID: 1047
Source: Userenv
Version: 5.2
Symbolic Name: EVENT_FAILED_READ_GPO_LIST
Message: Windows cannot read the history of GPOs from the registry. Continuing Group Policy Processing.
   
Explanation

Each time Group Policy Objects (GPOs) are processed, a record of all of the GPOs applied to the user or computer is written to the registry (in a GPO list). To optimize performance, Group Policy compares this GPO list to the current list to determine if there are any GPOs that need to be applied.

This event occurs when Group Policy is unable to read the registry to determine the list of GPOs that were applied last. Group Policy processing continues.

This behavior might occur if some values (such as Options or FileSysPath) are missing in subkeys of the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\History

When this occurs, Group Policy cannot be applied on the computer.

   
User Action

To troubleshoot this problem, try the following:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this behavior:

  • Use Registry Editor Regedt32 to check the permissions on the History key. Make sure that the permissions are:
    – Administrators (Read, Full Control)
    – Authenticated Users (Read)
    – System (Read, Full Control)
  • Delete all of the subkeys in the History key, and then refresh the group policy. To immediately regenerate the deleted keys in the registry, type the following command at a command prompt on the affected computer:
    secedit /refreshpolicy machine_policy /enforce
    The subkeys are re-created in the following key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\History
  • You can also check the Application event log for informational Userenv event ID 1704.
