The next major version of Windows, Windows 10, will be available late next year. The new operating system is being unveiled today at an event in San Francisco, where Microsoft announced its name and began detailing new features, including the return and makeover of the Start Menu, the introduction of multiple desktops, and a new universal search feature. Microsoft isn’t hiding that, for mouse and keyboard users, this is a move back toward what Windows users are used to and away from the contentious changes in Windows 8. “It gives the familiarity of Windows 7 with some of the elements of Windows 8,” Windows chief Terry Myerson says.
