If you do not press CTRL+ALT+DEL at the logon prompt, the Windows NT/2000 logon screen saver activates in 15 minutes.
You can manage:
1. What screen saver is used.
2. The screen saver timeout.
3. Whether the screen saver ever becomes active.
To change the screen saver:
Change the path and file name data string in the SCRNSAVE.EXE value name at HKEY_USERS\.DEFAULT\Control Panel\Desktop. If you enter an invalid path / file name, you will have to restart the computer in order to logon and correct your mistake.
To change the timeout:
Change the number of seconds data string in the ScreenSaveTimeOut value name at HKEY_USERS\.DEFAULT\Control Panel\Desktop.
To disable the logon screen saver:
Set the data string to 0 in the ScreenSaveActive value name at HKEY_USERS\.DEFAULT\Control Panel\Desktop.
