So my stepdad brought home this old tower from work running Windows XP. Whenever we log in it shows a pop-up windows that asks for a user name and password. It's not the typical lock-screen that Windows XP has, it's just a pop-up window on top of the desktop. Can't access anything without giving the credentials.
Is there a way to get rid of the account, or is he gonna have to track down the original user and get the password?
