Steven Sinofsky, the president of Microsoft’s Windows and Windows Live operations, is leaving the company, according to media reports. The announcement comes just days after Microsoft launched Windows 8. Sinofsky will be succeeded by Julie Larson-Green, who will head the Windows hardware and software division, Reuters reports. Tami Reller will take over responsibility for the Windows business, while retaining her posts as CFO and chief marketing officer. Both Larson-Green and Reller will report directly to Microsoft CEO Steve Ballmer.
