So what is Windows 7?

It's the next version of Windows for PCs, and it's the result of working hand-in-hand with our partners and with people who use Windows in the real world every day. We're paying particular attention to the things they're telling us are important to them and will make their PCs work the way they want them to—things like enhanced reliability, responsiveness, and faster boot and shut-down. We're also trying to make their everyday tasks easier, like connecting and syncing devices, browsing the web, and managing a home network.

Of course, we're also working on new capabilities, so people will be able to do things with Windows 7 that were difficult (or perhaps impossible) to do with PCs before. Finally, we're working hard to ensure that Windows 7 will run on any PC and work with any program that works today with Windows Vista, so upgrading from Windows Vista will be easy.
