I have problem with my laptop. It is a Toshiba Satellite 1415-S173. It was originally Windows XP and the guy I bought it from changed it to windows 2000 Pro. The guy also has a Administrator password on it. The problem I have is that I can't install anything withouth signing in as the Administrator, but I don't have the password and neither those he. (he forgot). He also doesn't have the reformatting CD. Is there any way I can change the password without buying the CD's???
