In the history of Microsoft , CEO change happened only twice : billionaire and philanthropist Bill Gates, left the post in 2000, and his successor emotional Steve Ballmer.
Gates said in one of his public appearances, that he and other members of the board of directors held a meeting with a lot of candidates for the vacant position. However, they still can't name or approve of the new Microsoft head.
Thus, among the favorites still listed former head of Nokia Stephen Elop and the current leader of Ford Alan Mulally.
