Title: How to Disable the Windows Logon Screen Saver in Windows XP

Objective: This demo describes how to turn off  the logon screen saver in Microsoft Windows XP. When you start Windows, you may be presented with the Windows XP welcome screen, which prompts you to click your user name to begin, or you may be presented with a Welcome to Windows dialog box that prompts you to press CTRL+ALT+DEL to log on. By default, if you do not press a key for 10 minutes, the Windows logon screen saver (Logon.scr) starts. This demo will show you how to disable that logon screen saver.
