Windows XP Choose User no password
If you only have one account on your Windows XP computer which does not have a password and it is asking you to “select” the account. It is possible to bypass this pointless selection by running this command in run (Start->Run or Windows Key and ‘R’)
Then un-check “User must enter a user name and password to use this computer”
That should solve your problem, let me know if this helps or not.
