Hello, I was recently given an HP Pavilion with Windows XP Media Center Edition 2002 SP2 installed on it. It hadn't been used for a long time and was (obviously) out of date. After spending an hour clearing off all the unwanted programs I then created and account and deleted the old owners, problem solved or so I thought. One of the updates went wrong and caused my graphics display to mess up so I used System restore to undo them, this however, somehow brought back the account I had just deleted and this time I forgot to create another account while before deleting the old one, leaving myself unable to do anything but log on as Guest. Is there anyway I can create a new Administrator account? or will I have to go buy a new windows disc and reinstall everything to get my computer back?
