There's a button (one of the "F" buttons) that you can press during boot-up that will provide access to the Administrator log-in. My admin account is messed up and I need to delete it. This is an XP machine.1 person got this answerI do too

Hi I got this problem it's asking me for a password when I log in when I only changed the name of admin in admin management I never opt to have a password or check the box for it to require a password so now when I boot up my name appears asking for password this was a old office computer running windows xp and was thrown out all I did was replace the motherboard and it worked great
