The Aero user interface adds a powerful enhancement to task switching. Alt+Tab still works—even better, in fact, because now thumbnails of each application are displayed, not just titles. But you’ll probably abandon Alt+Tab in favor of Windows+Tab, called Flip3D, which shows you a revolving set of windows at an angle so you can see exactly what you’re switching to.
You can reverse the order that Flip 3D cycles through your open windows by holding down the Shift key in addition to Windows+Tab. In my case, the Desktop window has always been displayed as the bottom-most application when I pressed Windows+Tab. To minimize all applications and display your Desktop, therefore, hold down the Windows key, then press Tab, Shift+Tab, and let go of the Windows key.
