Windows 8 is the codename for an upcoming version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs. 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 Delman, Microsoft’s vice president of global marketing, hinted in an interview that Windows 8 would have Xbox Live integration, similar to Windows Phone 7.
