I have inadvertently managed to remove all permissions to my C: drive so now its become read only and is obviously causing numerous problems.
I have tried booting in safe mode with command prompt and using the hidden Administrator account but whenever I try commands such as takeown and icacls all I get is 'Access denied' so I'm now at a loss as to how to reset the permissions so I can regain control.
..any help/ideas much appreciated before I format and do a clean Vista install!!
