Microsoft Corp. (NASDAQ:MSFT) said Eric Rudder will become its chief of research and development as current head Craig Mundie prepares to retire.
Rudder, 46, is currently chief technical strategy officer for the Redmond, Wash., company, the world's top software developer. He'd previously been a VP for software servers and also worked closely with developers.
Mundie, 62, is an electrical engineer with decades of experience designing computers as well as software. He's been with Microsoft since 1992 and was designated to take over many of the design functions Chairman Bill Gates, now 57, left, when he stepped aside from daily operations in 2006.
Mundie will remain an adviser on projects to CEO Steve Ballmer, 56, until he turns 65 in 2014.
