User Account Issues

Hello Folks,

I'm in Stockholm, Sweden living with a friend while I study. To repay her kindness I've been helping her with various things around the house. One of those things involves computers.

She has a Dell computer running Windows 7 Professional. She received this computer, which was originally destined for the Mexican embassy here in Stockholm, from a friend. The friend said that she would never be able to default her user account for start up. My ego and I agreed this was an oversight, and proceeded to 'delete' the Mexican account.

Now when I start up, it auto-defaults to the Mexican account, which isn't 'there.' When that fails, it kicks me back to the user log-in page. There it displays the Mexican account, or 'log in with another account' option. If I type in the name of the other users I left, I can log in, otherwise, I only see the Mexican account.

Once I log into the desktop, and log out, it shows the 'proper' result of her account, the one I credit for myself, and the guest account.

My question: how do I un**** this situation? And is it possible to truly 'delete' this Mexican account so this doesn't happen?

Thanks for any help provided, and time given.

Humbly,
Comrade
