Make XP auto login

Click Start > Run and type

CONTROL USERPASSWORDS2

Select the user account from the list (the account to which you want to automatically logon). Uncheck Users must enter a user name and password to use this computer option, and click Ok. Type the user account password and complete the process.

For Windows XP Home, don't try to auto-login as the built-in Administrator, as you'll receive an error message.
