Hide Running Program from Appearing in Taskbar or Traybar [Taskbar program hide via hot key]

While being quite an old utility, the Window Hide Tool has several options available which allow you to not only hide and show application windows with hotkeys, but also has the added options of setting a password if you want to show a window, close an application and if you want to protect the hide tool configuration window. The tray icon itself can be turned off to stealth it from the average users, or you can leave the icon enabled and have quicker access to hiding and showing all or specific windows.
