Home Screen and Desktop

The new Windows 8 Home Screen is diaplayed after setup completes and when the system is started:

Windows 8 start screen

 

The Windows 8 "Desktop" is accessed by clicking or tapping (on a touch device) on the "Desktop" icon:

Windows 8 Initial Desktop

Note that the desktop no longer has a "Start" button by default.

Moving the mouse to the corners of the display shows new Windows 8 options - however there are no icons or visual cues to indicate that this is possible.
