How do I make a Windows XP PC automatically login?

If you want to have a Windows XP automatically log in (on a domain or not), you can use the Tweak UI tool available here:

You’ll need to be an administrator to install it.

There will be a Login category on the left side where you can type in the user name and password that should auto login every time you start up.

Be aware that the password is stored plaintext in the registry, so do not use if that’s a problem. You could use this, for example, on TA lab computers where everyone knows the password anyway.

To avoid auto login, hold down the left shift key when Windows starts up.
