Windows division head leaves Microsoft

  • Steven Sinofsky, the head of Microsoft's Windows division, has left the company with immediate effect.

    His exit comes just weeks after Microsoft unveiled Windows 8, the latest version of its flagship product and vital to boosting the firm’s future.

    Microsoft did not give any reason for Sinofsky's departure.

    However, speculation has been rife of an internal "war" between Sinofsky and chief executive Steve Ballmer.

    Stock markets reacted to the news poorly, with Microsoft's shares shedding 4 percent of their value in Tuesday morning trading on Wall Street.

    Julie Larson-Green is to be promoted to lead all Windows software and hardware engineering, Microsoft said.
