FILE - In this Thursday, Oct. 25, 2012, file photo, Steven Sinofsky, then-president of the Microsoft Windows group, delivers his presentation at the launch of Microsoft Windows 8, in New York. Microsoft shares slid more than 4 percent before the opening bell Tuesday, Nov. 13, 2012, after the software company revealed that Sinofsky was leaving. Sinofsky's departure comes just weeks after Microsoft launched Windows 8, a major overhaul of the operating system that's used on most of the world's computers. (AP Photo/Richard Drew) less
