So I sometimes get irritated when I install a new computer with Windows XP and have to deal with the login menu each time.  For many computer users, they have their own personal system and they do not share the computer with anyone.  If the customer is not worried about security, they can adjust some simple settings that will cause the computer to automatically log in as their user when they turn on the computer.  To access these settings in Windows XP (Home or Professional edition), the user must click the Start Menu and select run, then type CONTROL USERPASSWORDS2.  The rest of the settings are easily configured from the console that pops up.  And that is how to get your computer to automatically login a user when you start it up.
