Have you ever been in a situation where your boss finds you playing games or chatting with your friends online? Then you should be using Magic Boss Key, a freeware tool which can quickly hide active application windows with a hotkey. You can hide the browser windows, folder windows, applications windows, all your desktop icons and taskbar when your boss or anyone else you don’t want to see your screens comes in.
When you open the application, it shows all the applications which are running on Windows. You can set the hotkey for hiding all application windows from the options. The app sits in the system tray and then hides all windows when you hit the hot key.
