Changing Default Logon Screesaver
Before a user logs in, XP has a default screensaver which in some cases might be annoying. This note explains how to change it.
Changing the default Logon Screensaver in XP

Run | regedit

Navigate to

HKEY_USERS\DEFAULT\Control Panel\Desktop

There are 2 main keys to adjust:

Change the value of "ScreenSaveActive" to "0" to disable or "1" to enable the login screen saver.

Change the value of "SCRNSAVE.EXE" to the full path and filename of the screen saver .SCR file. For a normal XP system a good choice would be logon.scr
