The known site Kotaku has released a note this morning, Steve Ballmer, Microsoft chief after the retirement of Bill Gates, addressed to all employees where we talked about some changes at management level, from autumn Robbie Bach The current head of the entire entertainment division, and J Allard, best known for being one of the key figures behind the launch of Xbox and Xbox 360, leave their posts.

Bach, Microsoft employee for 22 years during which he worked on many successful projects such as Office, everything about the Xbox brand, including even the Halo brand, and Windows Zune Phone, said he reached a point in their life when changing priorities, it wants to focus more on family and its non-profit activities.

As for J Allard, who worked for the Redmond for 15 years, have been partially denied rumors in recent days who wanted to abandon due to disagreements with the same Ballmer. These items, however, seem incorrect, since Allard Ballmer will continue to work directly with the company as outside counsel on issues such as design or user interfaces.

To meet the abandoned, partially Ballmer decided to change the attitude within the company, now Don Mattrick and Andy Lees in July will communicate directly with him, but David Treadwell will keep informed Mattrick.
