the User Accounts options in Control Panel?
Open up User Accounts, select "Change the way users log on or off".
In the next screen, change the option for "Use the Welcome screen", (check the Logon options help link on the left).
When changed, OK/Apply out, reboot and see what difference there is, but make sure you know what the passwords are.
Go back into Control Panel and User Accounts if necessary, and reverse the option. Reboot again.
Does this get you back to where you want?
