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.

We hope this helps you find what you're looking for. Please check back soon.
