Some of the leaked and rumored features that we will see in Windows 9 are the return of familiar desktop look, a Start Menu, the removal of the charms bar, virtual desktops, and Cortana integration. Virtual desktops allow you to setup different virtual screens that you can launch programs or open documents in. This allows you to open a browser in one desktop, your homework/work in another, and games in another with the ability to easily switch between them. Cortana is a personal assistant similar to Apple's Siri.
We will keep everyone updated as more information is released. In the meantime, if you wish to discuss Windows 9, feel free to head over to our new Windows 9 forum.
