Dean Hachamovitch, the Corporate Vice President of Internet Explorer, is taking on a new role at the company.

Hachamovitch is taking on a new job on a new, unspecified team after working on IE for the past nine years, he blogged on November 11.

"I’m changing roles at Microsoft, and excited to start a new team to take on something new," Hachamovitch said in his post.

I asked Microsoft officials if they're commenting on his next position or who will take his place heading up IE. A spokesperson said Microsoft execs had no comment beyond Hachamovitch's blog post, in which he noted he is leaving his post as Corporate Vice President of IE.

Update: One of my sources said that there will no longer be a single "chief" of IE in the new, post-reorg world order.

Update No. 2 (November 12): Two of my sources have said Hachamovitch is moving to a new data sciences team inside the company. One of those sources says this will be a team that dissects Microsoft telemetry data from across the company to improve products and make predictive decisions about strategic direction.

Hachomovitch's move isn't unexpected. Terry Myerson, the head of Microsoft's new unified operating system division, is putting his own core team in place . The unified operating system engineering unit encompasses Windows Phone, Windows/IE, SkyDrive and the Xbox One operating system.

In Myerson's new org, David Treadwell is the new head of program management; Mike Fortin is the new head of test; and Henry Sanders is the new head of development. Treadwell was most recently on Xbox, Fortin on Windows and Sanders on Windows Phone.

Many of the Windows leaders who reported to S teven Sinofsky when he ran the Windows business up until a year ago have moved to other divisions and/or are seeking new positions (possibly in other parts of the company).

Microsoft is continuing to forge ahead with IE. Just last week, Microsoft made available the release-to-Web version of IE11 for Windows 7 .
