Julie Larson-Green has been appointed leader of Microsoft's new Devices and Studios Engineering Group, taking charge of the Xbox brand.

Larson-Green replaces ex-Interactive Entertainment Business president Don Mattrick who left the company earlier this month to join social games firm Zynga.

Larson-Green previously served as the head of Microsoft's Windows division.

The Devices and Studios Engineering Group has been introduced as part of a major corporate restructuring at Microsoft, replacing the firm's previous Interactive Entertainment Business and housing all hardware development under a single group.

Larson-Green will take responsibility for Microsoft's "studios experiences", including "games, music, video and other entertainment".

Meanwhile, Xbox One's operating system development will continue under Microsoft's new 'Operating Systems Engineering Group' headed up by Terry Myerson.
