The new Windows 8 operating system has the usual keyboard shortcuts, just like all the previous versions of Windows did but with extras. The difference is, Windows 8 has such a new interface, that it might be easier to use keyboard shortcuts. For example to shut down Windows 8 there are 4 steps, using a keyboard shortcut there are less steps.
Please Note: If you’re new to keyboard shortcuts, you will need to get very familiar with the Windows key on your keyboard. It is located to the left of the space-bar. So when it says “Windows Key” it means you need to hold that key down and press the other keys required.
So let’s begin…

Windows Key + D:
While on the Windows desktop this key combination will clear all the open windows and show the Desktop, a second press of the combination will reopen all the windows previously hidden. If this combination is pressed while on the Windows 8 Start Screen the Windows desktop is displayed.
Windows Key + F:
Brings up the files search menu
Windows Key + W:
