I wanted to change the security permissions of some folder, but I targeted my root D drive instead.
I cancelled half way, but still; the majority of the files is affected and I want to revert my action.
Some people suggest that reverting back to a system restore point should fix the issue. Although this sounds great I am a bit sceptical and my nearest restore point is way back.
Can anyone confirm that security permissions are reset to the restore point's permissions?
