Except Steven Sinofsky, longtime head of the Windows division and one of the internal forces preventing Microsoft from going in alternate directions, was pushed out under Ballmer's tenure, not Nadella's.
Granted, Ballmer made the mistake of putting Terry Myerson, who headed up the failed Windows Phone effort, in charge of Windows but that's another story.
