Steven Sinofsky, chief of the Windows division at Microsoft, has left the company with immediate effect.
Just two weeks following the launch of Windows 8, Sinofsky's move has left many questioning the purpose behind his shock move.
Whilst no official reason has been given as to the motive behind his resignation, rumours are rife about his reportedly aggressive work ethic playing a huge part in his departure.
Sinofsky gave the following statement: "It is impossible to count the blessings I have received over my years at Microsoft. I am humbled by the professionalism and generosity of everyone I have had the good fortune to work with at this awesome company."
It's been reported that Julie Larson-Green will take over of Windows software and hardware engineering, whilst CFO Tami Reller will maintain the Windows business. As President of the Windows Division, the former Microsoft executive was responsible of Windows 7 and the ill-fated Vista launch; continuing with his responsibilities to manage last month's unveiling of Windows 8.
"I am grateful for the many years of work that Steven has contributed to the company," said CEO Steve Ballmer in a statement. "To continue this success it is imperative that we continue to drive alignment across all Microsoft teams, and have more integrated and rapid development cycles for our offerings."
The sudden revelation comes just weeks after Apple reshuffled its executive board, with CEO Tim Cook dismissing head of the iPhone software department Scott Forstall as well as senior VP of retail John Browett.
With many a shake-up happening in Silicon Valley, it'll be interesting to see what lies ahead for two of technology's biggest rivals.
