Cant change "Power Option" after update.

Evening everyone. I have a problem i cant solve.
After latest update i can't change the "Power Options" for "Turn off display after:" Its greyed out on 10 minutes, saying "Some settings are managed by your system administrator".

Now, the computer is not in a domain, i've checked gpedit.msc, can't find any trace of this.
If i try change it using command prompt i got the same error, just that a policy overrides, so it cannot be changed.

Last resort is to reinstall, but i don't want that, hence i ask you lads first!

Are you Administrator?

Open the Command Prompt by typing cmd.exe into Start Menu, right-click on Cmd.exe, and open it as an administrator.

Execute following command and paste the command output to your next post:

Code:
