Steven Sinofsky

Company: Microsoft

Microsoft just lost a potential successor to CEO Steve Ballmer. On November 12, about a month after the debut of its new Windows 8 operating system, Steven Sinofsky left the company. Sinofsky was the head of Microsoft's Windows division, and at his post, he led the effort to make the new operating system work with PCs phones and tablets. Sinofsky's successor, Julie Larson-Green, will have to carry the torch.

"It is impossible to count the blessings I have received over my years at Microsoft," Sinofsky said in a Microsoft (MSFT, Fortune 500) press release that portrayed the transition as amicable. Though Sinofsky was considered a skilled and driven leader, he wasn't known for working particularly well with others. That's a rough trait for a leader, especially in the increasingly collaborative tech industry.
