I am trying to provide a way for user to [totally] disable the overlay extension, and enable them later if they want, without having to go through the pain to remove the shell extension from windows registry. > If you want something specific to your app, then your shell extension code > could check some kind of flag/event/whatever and then refuse to do anything > - but that isn't "killing" it.
