A new Administrator account popped up

[the shoe]

I put W7 (RC I got free from school) on a couple weeks ago. It use to boot up and go to the desktop. Now theres a log-on screen with 2 accounts. An Administrator account and My account, which I am the Administrator. Any ideas on how this new Administrator got created and how I can get it off the log-on screen? Id like it to go right to the desktop. Also I want my account to be the only one on there, but I cant delete this new "mysterious" account.....weird.

I'm the only one that uses computers in the house so I know it wasnt someone messing around with it.

Thanx

Did you try going into user accounts and removing it.
