Event 8194, The Client-side extension could not remove computer policy settings for { } because it failed with error code '0x8007000d The data is invalid.' See trace file for more details.

I am seeing this error in the application event log on a few Windows 7 clients.
"Event 8194, The Client-side extension could not remove computer policy settings for { } because it failed with error code '0x8007000d The data is invalid.' See trace file for more details."

Resolution:


- Log on to the machine
- Open Windows Explorer
- Navigate to %ALLUSERSPROFILE%\Application Data\Microsoft\Group Policy\History
- Delete all subdirectories under History.  (Please note %ALLUSERPROFILE% would be c:\programdata)


- Open a command prompt
- In the command prompt, enter gpupdate /force
- Verify that subdirectories will populate under %ALLUSERSPROFILE%\Application Data\Microsoft\Group Policy\History

Note: %ALLUSERSPROFILE%\Application Data\Microsoft\Group Policy\History contains a copy of the preferences contained in GPOs. If the copy process failed somehow, an invalid XML file may be left in one of the subdirectories, thus creating the 0x8007000d Error. By following the method described above, a clean copy of the GPOs is created and the GPO is working again.

Also, The following GUID registry keys under both of the following will need to be deleted too.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\History
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\History
