Another way to get yourself admin access

Pull out the network cable out of the back of the computer;restart the computer and boot into safe mode, usually by pressing F8 or somthing similar, this will bypass the main login and you should have admin.. Then plug the network cable back in, and edit the user accounts to give your account admin access. Then restart the computer normally, log onto your account, and if done right, you will have admin access. <<<>>
