I can't either do System Restore, or any else systemtools, that requires access to the C-drive.
I was borrowing my PC to a friend, so he could watch movies on it.
but I didn't want him to see all my prive stuff on the computer..
So I maked him an account.
but there was still stuff on my C-drive.
I went to My Computer -> properties -> security -> Advanced -> change permissions, and removed all the permissions there.
It says that only "the owner" can change it again, so i thought it was me.
But now I cant get access to my c-drive, or do anything that requires applications through the C-drive (also Windows operations).
So I can't copy, or delete ANYTHING on my Desktop, og the D-drive.
Can anyome help me to figure out, how to get the freaking access to the c-drive again?
Please people, help me.
