|This is on my own personal computer. I am the only person who uses it, however recently it was 'borrowed' by someone who has now messed up a bunch of account settings and I can't seem to change them back.|
The computer used to have two administrator accounts on it: mine, and a guest account for friends/family to use (which is effectively empty, no files, etc). I'm already aware this was a stupid way to set things up and I sure as hell won't be returning things to these settings, so don't bother berating me on that point.
My account has now been changed to a standard account, and the guest account is a password protected admin account. I do not know the password. (The b---tard who 'borrowed' my computer does, but they won't be cooperating.)
I would like to change my account back to administrator, but I can't do this except from within an admin account, which I now cannot access. Can anyone suggest a good way to do this?
