Open Control Panel, User Accounts, Manage Another Account.
- Disable Guest account.
- Make sure there is at least one user, with known password, set as "Administrator"

If you want another user to log-on automatically: Start | Run, type "control userpasswords2" (without quotes). Remove checkmark from "Users must enter...", and select the user you want to auto-logon
