Thanks for sharing your idea, I appreciate it! I think you are referring to the screensaver version, because the regular Windows version already shows "finished", and the last diskmap. Not a black screen. The first versions of the screensaver did the same, but somebody commented -rightly so- that a screensaver should not leave text on the screen burning into the phosphor. So now you can choose a secondary screensaver in the screensaver configuration, which will be started when the defragger has finished (--does not work for everybody
). Default is no secondary screensaver, just a black screen.
