A month after leaving Microsoft, the former head of the Windows operating system, Steven Sinofsky, is taking up a new role teaching at Harvard Business School.

Sinofsky announced the news on his Twitter, indicating that he will be taking up his post in spring 2013.

"Excited to return to @HarvardHBS to teach again this spring!," said Sinofsky. "New perspectives, recharge, share experiences, write."

When asked what he will be teaching, Sinofsky said he was going to be an "Executive in Residence."

"Research, writing, classroom on prod dev, planning, collaboration, and more," said Sinofsky.

Sinofsky served as president of Microsoft's flagship operating system, Windows, from 2009, where he led development of Windows 7 - the most successful rollout of a Windows product since Windows 95 more than a decade before.

More recently Sinofsky led the team working on Windows 8 which was released in October. However, his role led to growing tension between him and senior managers at Microsoft, including CEO Steve Ballmer. In November, he left the company in what Ballmer said was a mutual decision.

However, former Microsoft engineer Hal Berenson suggested recently on his blog that Sinofsky's departure was due to his failure to bring the Windows Phone division under his control, although the former Windows boss has denied the same.

Sinofsky's role as head of Windows has been divided between Julie Larson-Green, who is in charge of software and hardware engineering for the platform, and Tami Reller, who is responsible for the business of Windows.

Sinofsky's news role will be the second time he's had a teaching job at Harvard. In 1998 he served as "visiting scholar" at the Ivy League University.
