Hey,

Yeah - the User Accounts option in XP's control panel is a little misleading.

To delete an account in XP (Home or Pro) it is better to do it the ole 2000 way.

Control Panel > Administrative Tools > Computer Management > Local Users and Groups > Users

You'll see all the users (incl Guest) listed here. Highlight and right click to delete.

There is a registry way to do this but this is probably the easiest.

Hope it helps

P.S. Make sure your Control Panel is set to "Classic View" - The fisher price toys-a-like alternative is less than useless for doing anything.
