Microsoft said Chief Research and Strategy Officer Craig Mundie, 63, plans to retire in 2014 after two decades at the software company and has shifted to a new role as a senior adviser to CEO Steve Ballmer.

Eric Rudder, chief technical strategy officer, is taking over some of Mundie's duties overseeing research, privacy and security, as well as technology policy, Ballmer said in an email to staff Dec. 14 that Microsoft made public Monday.

Mundie was responsible for Microsoft's early efforts in software for handheld organizers, cars and televisions. He also developed technology policy in areas such as privacy and security, and oversaw the Microsoft Research unit and the company's technology-policy relationships with governments such as China and Russia.
