Windows 7 is Microsoft's PC operating system which was released in October 2009. Intended to be an incremental upgrade to the Windows line, Windows 7 is compatible with applications and hardware with which Windows Vista is already compatible. Features include multi-touch support, a redesigned Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements.
What is Windows 7?
Your PC, simplified
You told us to make Windows simpler and easier to use. We listened. Windows 7 has better ways to find and manage files—like Jump Lists and improved taskbar previews—to help you speed through everyday tasks. It's designed for faster and more reliable performance, so your PC just works the way you want it to. With 64-bit support, you can take full advantage of the latest powerful PCs. And great features like HomeGroup, Windows Media Center, and Windows Touch make new things possible.
