I'm running Windows XP Pro I have an Account Unknown. I can't find out what or who this is. It does not show up on Control Panel User Accounts but does under My Computer User Profiles. How do I identify and remove it? Thanks in advance for any and all help.

Try: start > Run... > control userpasswords2

The Owner account is displayed as "Account Unknown" in profiles on Xp Home
(I briefly ran XP Home before Pro installed)
