No longer front and center, the Desktop is reached by clicking the Desktop tile on the Start screen. When you get there, you'll see a visually simpler, flatter interface than in Windows 7. And one major navigational feature, the Start button, has been removed.
Otherwise, it behaves pretty much like the Windows 7 Desktop, with icons for launching your traditional Desktop applications and a taskbar that shows currently running apps. Note, however, that you can't run the new Windows 8 apps from the Desktop.
