Steven Sinofsky

President, Windows and Windows Live Division
Microsoft Corporation

Sinofsky, who has been at Microsoft since 1989 and had run the development of Office, was brought in to create a new version of Windows after the Vista calamity, and succeeded with Windows 7. Now, he is working on a new version that will not only power PCs, but adapt Windows for tablets, where Microsoft is already behind. But, hey, no pressure. As president of the Windows and Windows Live Division, Sinofsky has accountability for the overall Windows business, from development to business strategy and marketing for Windows, Windows Live and Internet Explorer. So now you know who to call when your Windows system freezes up. Sinofsky holds an undergraduate degree with honors from Cornell University and a master's degree in computer science from UMass Amherst. If you get the chance, ask him about his stint in Beijing, China, where he worked on projects in sales, marketing, and research and development.
