Windows 8 is the next big leap from Microsoft for widening their presence in mobile, tablets and desktop as well. Window 8 is currently available in developer preview, and you can download it from dev.windows.com.
Windows 8 has new UI, which is evolved from Windows Mobile 7 Metro user interface. I would like to share a theme which is available for Windows 7 desktop operating systems to get a feel of Metro UI and Windows 8 interface.
Thanks to jaycee for his splendid work. Download the Metro UI.
