If you use the option (step 2) below that will play a sound, then it will play the
Windows Logoff Sound.wav to indicate the screen saver has been disabled (turned off) and the
Windows Logon Sound.wav to indicate the screen saver has been enabled (turned on).
When you toggle the screen saver to be enabled using this context menu item, Windows will still use the same
screen saver that you had set to run before you toggled it disabled.
