Microsoft unveil the next version of Windows

• Microsoft called Windows TH the "next version of the Windows client operating system.
• The most significant visible update to the Microsoft 9 system will be the return of the start button and menu, which was replaced by a tiled start screen in Windows 8. The new button is a mixture of the classic Windows start menu and the tiles introduced in Windows 8.
• The Charms sidebar, a menu accessed whenever a user swiped their mouse to the right side of the screen, has been eliminated from devices not accessible by touch.
• In an improvement that could excite businesspeople and I.T. technicians, another rumor speculates that the new O.S. will support virtual desktops, allowing a user to run multiple desktops at once from a single computer.
• One big unknown, however, is what the next version of Windows will be called.  
• Microsoft recently said Windows (9) would be a free upgrade for Windows 8 and 8.1 users.
