Blair,
Click Start, and then click Run. In the Open box, type control
userpasswords2, and then click OK. In the dialog box that appears, enable
Users must enter a user name and password to use this computer check box,
and then click Apply.
Then, to enable automatic logon to the other user account, select the user
account from the list, and then uncheck the "Users must enter a user name
and password" box. Input the username and password.
