Automatically turn off screensaver when doing defrag

If the Screensaver starts running while performing a defrag of a HDD partition then the defrag will take forever.
So if one has fallen in love with the screensaver, but don’t want the hazzle of turning it off before starting a defrag, then this can be a help.

Update the following STRING values :

[HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Applets \Defrag \Settings]
(Default) = “YES”
DisableScreenSaver = “”

Note the screensaver will not be disabled if the Defrag is run as a scheduled task.
