As the corporate vice president of the Windows eHome Division at Microsoft Corp., Joe Belfiore is responsible for development, business management and marketing of Microsoft Windows XP Media Center Edition and related devices, including Media Center Extender and the Media Center DVR. He also leads development of Media Center for future versions of Windows. A huge consumer advocate, Belfiore believes the Media Center vision and mission is revolutionizing the way people think about and use personal computers, transforming PCs from mostly productivity devices to the primary entertainment hub for digital convergence in the home. Before moving to the eHome Division, Belfiore was product unit manager for the Windows User Experience team throughout the planning and development of Windows XP. In that role, he was responsible for the overall user experience of Windows — both as a manager of the engineering and design team that created most of the Windows XP user interface and also as a key driver of positive user experiences across all versions of the Windows operating system. Fresh out of Stanford University, in 1990 Belfiore began his career at Microsoft as a program manager on OS/2. Shortly afterward, he drove the design of the first Windows NT® user interface, then became the lead project manager for the user interface of Windows 95. He then acted as group program manager for Internet Explorer 4 and the Windows 2000 user interface before beginning his work on Windows XP. Just before taking on his current role, Belfiore served as general manager of the Windows eHome Division, during which time he drove the development and shipment of four versions of Windows XP Media Center Edition and expanded product availability from three countries to 33.
