2. Steven Sinofsky, President, Microsoft Windows Division
You have to be a maverick to deliver a product like Windows 7 inside the byzantine bureaucracy that is Microsoft. By all accounts, Windows 7 represents a dramatic improvement over its much maligned predecessor, Vista. Before straightening out the Microsoft operating system mess, Sinofsky had worked wonders with the other big Microsoft franchise, Microsoft Office. He isn't swayed by Microsoft's high-powered politics. He's all about results. Sinofsky has become Microsoft CEO Steve Ballmer's go-to-guy. And he could very well be the next CEO of Microsoft.
