Have you ever wanted to hide certain programs from people that may be looking over your shoulder? If so then the free program, Window Hider is for you.

You give Window Hider a list of programs and a shortcut key then when it detects you pressing that shortcut key it hides those windows in your list.

While the author makes the case of using this to hide programs from your boss (which I do not endorse by the way), I could certainly see this being useful for quickly hiding password programs or when you are looking at banking information on a browser.
