When I left my previous company they let me have an older computer but never removed my system administrator. They will not help me with this because I no longer work for the company. I want to bypass system administrator and set up a new one I have xp and it wont let me remove it????Help

You could also use NTPWEdit which will simply overwrite the password SAM file:
