Andy Lees, senior vice president of Microsoft's Mobile Communications business, has been promoted to president by company CEO Steve Ballmer. He'd been running the department since earlier this year after Robbie Bach, president of the Entertainment and Devices Division, announced his retirement plans.
In a memo that also saw Kurt DelBene announced as president of the Microsoft Office Division and Don Mattrick become president of Microsoft's Interactive Entertainment Business, Andy was described as "a proven leader who knows what it takes to win against the toughest competition".
He'll continue to oversee marketing and product development for Microsoft's mobile phone products, including Windows Phone 7.
