Minimize all open windows using Aero Peek

Aero Peek is a Windows interface feature that lets you "peek" at the Windows desktop, getting a quick view of it. Activate Aero Peek by left-clicking the bottom-right corner of your screen.

If you have several windows open at one time, minimize them using Aero Peek (Show Desktop) icon on the Windows Notification Area on your taskbar. The Show Desktop minimizes all open windows to access your desktop.

To re-open all previously minimized windows, click the Show Desktop icon again and they all reappear.

Also, to view the desktop without actually minimizing all screens, use Peek. Hover your mouse pointer over the Show Desktop icon without clicking to view your desktop momentarily without minimizing anything.
