Because of the nature of Windows, there is only one window that is active at any given time, and that window gets all your focus, including your keyboard, mice, etc. All other open window are inactive. If you have many windows open at the same time and would like to clean up the clutter a little bit by minimizing all inactive window, how easy would that be?
Other than a nice Aero Shake, here is another deadly simple way of doing so. Simply hit
Windows Key + Home key
And all inactive windows instantly disappeared. Give it a try. It’s that simple.
So how to minimize all windows at once then? Hit
Windows Key + D
Well, it doesn’t really minimize all windows. It just calls up the desktop to cover all the display windows.
