#4: Get to the Desktop Quickly
You might be used to the Show Desktop shortcut on the Quick Launch toolbar in previous versions of Windows. However, in Windows 7 it's even easier to access the desktop.
Simply click the button on the far right of the Taskbar, next to the time and date (see Figure 5).
If you have a Windows Aero theme enabled, as in Figure 5, hovering over the Show Desktop button makes all the windows transparent and lets you preview the desktop.
