Previewing Windows 8

 Microsoft News Center
 
Video on this introduces some basic elements of the new user interface. Although we have more to disclose on our developer program, BUILD (September 13 to 16 in Anaheim, California)

The demo showed some of the ways we’ve reimagined the interface for a new generation of touch-centric hardware. Fast, fluid and dynamic, the experience has been transformed while keeping the power, flexibility and connectivity of Windows intact.
Here are a few aspects of the new interface we showed today:
Fast launching of apps from a tile-based Start screen, which replaces the Windows Start menu with a customizable, scalable full-screen view of apps.
Live tiles with notifications, showing always up-to-date information from your apps.
Fluid, natural switching between running apps.
Convenient ability to snap and resize an app to the side of the screen, so you can really multitask using the capabilities of Windows.
Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.
Fully touch-optimized browsing, with all the power of hardware-accelerated Internet Explorer 10.
