How to change the logon screen saver in Windows

SUMMARY

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. This step-by-step article describes how to change the default logon screen saver. When you start Windows, a Begin Logon dialog box prompts you to press CTRL+ALT+DEL to log on. By default, if you do not press a key for 15 minutes, the Windows logon screen saver (Logon.scr) starts.
