Not everyone needs to log in to use a PC. If you feel that a login is unnecessary for the application or setting that you use an XP PC in, you can set XP to require a username and password. Go to Start -> Run -> “control userpasswords2″ and press enter. Uncheck the box that reads “Users must enter…” and press “OK.” Say goodbye to user names and passwords, but remember that doing this makes your PC very insecure.
