The main feature that was shown is the extensively redesigned user interface. The Start menu is replaced by the new "Start screen", which includes live application tiles.
The user can return to the regular desktop by choosing a "Desktop" application. Examples of applications on the Start screen include a weather application, Windows Store, Investments, RSS news feeds, user's Personal Page, and user's Windows Live Account. The new interface is primarily designed for 16:9 screen resolution, with 1366×768 and larger screens able to display two Windows 8 applications using "Snap". 1024×768 screens can display one Windows 8 application in full-screen, and 1024×600 screens can only use the traditional Windows Desktop. It has been confirmed by Microsoft that PCs with mice and keyboards can also use Windows 8.
Microsoft also announced that Windows 8 will use the processor and the physical memory more efficiently, to make Windows run more smoothly.
Mike Angulo confirmed at Computex 2011 that Windows 8 would use OEM Activation 3.0 instead of Windows 7 OEM Activation 2.1 which will make it less prone to hacks.\
