Windows unit president Steven Sinofsky is leaving the company, effective immediately, AllThingsD has confirmed.
The move comes less than a month after Sinofsky presided over the launch of Windows 8 and Microsoft’s Surface tablet–products seen as key to the future if the PC software pioneer is to retain its position amid a market increasingly dominated by phones and tablets.
Sources have said the move came amid growing tension between Sinofsky and other top executives. Sinofsky, though seen as highly talented, was viewed at the top levels as not the kind of team player that the company was looking for.
Sinofsky has been widely reputed to have an abrasive personality for years, so one really has to wonder at the proximate cause of his departure. Still, team player or not, Sinofsky has to get credit for the Microsoft recovery from the Vista debacle with Windows 7.
The official press release is even more opaque as expected, but here’s the new leadership:
Julie Larson-Green will be promoted to lead all Windows software and hardware engineering. Tami Reller retains her roles as chief financial officer and chief marketing officer and will assume responsibility for the business of Windows. Both executives will report directly to Microsoft CEO Steve Ballmer.
