how do i change which USER ACCOUNT in XP loads automatically upon Boot up?

Answer 1

TWEAK UI is your friend, it is a power toy from MS.

Answer 2

You cant, with multiple users, it will always display the user select screen.

If you refer to you are the only user, and you have a Guest user also, then you can remove that account to make you the only user to boot automatically.

Answer 3

ok, when u have only one user account it will start with that one if u dont have a password activated, if u have more than one it will ALWAYS ask u which one u want to log on with.
