I had admin privilegies on my work pc (by an accident), and then I did (by accident):
"Run cmd.exe with administrative previlliges and type
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
And now I am a limited user again, please help me undo this.
I did not have the intention to do this, I thought this would remove the "blocked by group policy" rule thing.
