Question : Grant user permissions to powercfg registry keys, not working

I am using the powercfg to change power settings via group policy on windows xp machines.  I followed instruction in article how to use powercfg.exe to creatge a group policy for power schemes in windows xp http://support.microsoft.com/kb/915160/en-us.  The login script runS but only has required permissions if I manually give users full permissions to the registry keys MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg
USERS\.DEFAULT\Control Panel\PowerCfg
I have setup a gp to do this but doesnt appear to be working.  I logged on more than once with no success.  
It would appear that I have another overriding policy which I cant find as even when logged on as administrator I could not change the permissions on the registry key.  I could only change by logging on as the local administrator.

It is not a huge issue as I can manually go to each PC and change registry settings it just isnt very good long term.
Any suggestions?

Answer : Grant user permissions to powercfg registry keys, not working

It looks to be GPO is not applying on the system.

Run gpresult to find list of the policies applied & RSOP.MSC to see the actual policu applied on anyone domain system with the problem.

You can enable usernv logging to see the policy applied in details on any of the client machine.

Its the best way to troubleshoot the GPO not applying issue.
