Your Windows desktop stores important shortcuts that allow you access to your programs and files. You may also have gadgets that let you track stocks, weather, headlines and other useful information. To restore your desktop quickly in any modern version of Windows, you can use a quick keyboard shortcut. In Windows 7, you can also click on the bottom-right corner of your screen, just to the right of the clock, to toggle your desktop view on and off, or simply hover your mouse over that area to make your windows translucent so you can view your desktop without minimizing any windows.
Locate the Windows logo key, which is generally in the lower-left region of your keyboard.
Press the Windows logo and the "D" key simultaneously to minimize all windows and restore your desktop view.
Press the same key combination to restore the windows you had open after you are finished viewing the desktop.
If you launch a window after pressing the shortcut combination, the keys will simply minimize that new window and reveal the desktop again. Pressing "Windows" and "D" again will then toggle you back to the most recent view--in this case, only the newly opened window.
