XP keeps asking for a password. There was never one set. Even when you try to go into "Recovery" it ask for a password. What happened was my brother recieved the error about windows couldn't start because one or more files were corrupt. So I sent him the fix. He fixed it, then he started to mess around and so when he rebooted then all of a sudden it started to ask for a password. I am wondering what is the default password.
