ok ive done this but, i need the administrator password, the thing is its an ex work pc my dad was given and since he got it hes left the place he worked. i dont know the pass and i dont think he does is there any way to reset it or something? ive tried all the standard ones, admin, password etc. one of my mates also said there is another option. i do have windows xp startup disks and he said that if i booted from that if i choose upgrade instead of full install then it would install xp on my computer (thus fixing the problem) without deleting anything from my hard drive. would this help to fix my problem and would i need the administrator password for this too?
