Can someone tell me how to get rid of the "Windows Log On Screen" that appears on some (not all) installations of XP Pro? I have two machines both running XP Pro installed from the same disk and kept completely current by Microsoft. One displays the screen on every bootup and one never displays it. To be clear, I'm not talking about the greeting screen that can be turned on/off in the user account. The screen I mean is the one with the blue background and a simple login box asking for a password. Actually, you don't even need a password. If you click "OK" or press "enter" the screen disappears to be replaced by a desktop. Thanks in advance.
