Deleting account

[Tamara]

When I installed my daughter's (4 years) computer, Windows XP created 2
accounts.
An "Administrator' account with the name "Administator" and a "Guest"
account.

I created 3th account for her, with limited access to prevent her from
deleting System files or change settings, and choossed for a "welcome
screen" for logging in with out pictures.

Last week, her nephew stayed a few days, and I noticed today that another
account was created, named "Test" with Administrator priviliges.

My account (the original administrator account) was not available anymore on
the welcome screen, although it was still accessible trough the old login
screen.

I tried to delete this account (Test), but with no succes.

Is there an (easy) way to delete this account and restore the computer back
like it was?

Did you try booting into safemode? Right when you press the powerbutton
on your computer to start up keep pressing F8 until a different screen
comes up that asks if you want to go into safemode. Go into it. You
should be able to login to any account. Even "Administrator" should
show up there. Go into any account with administrator privelages and go
to control panel then account settings and you should be able to remove
the account with no problems.
