Introducing Windows Home Server, a new way to simplify how you keep and share your family's photos, videos, and music.
This smart hub lives in your home and connects all the important people in your life to the good stuff that's on your computers. You can pump your family's tunes to your Xbox 360, share baby pics over the Web, and even get on your home server when you're not home. Friends and family can see and share any files you want, whether they're in another room or another country.
Your family's memories stay safer, too, with daily automatic backups that help you recover lost documents (or rescue computers that have had unfortunate accidents). Adding space to the server is also easy. So don't worry about recording too many vacation movies—Windows Home Server will keep growing and getting better.
You can find Windows Home Server through retail stores and Web sites in a wide range of new hardware products, starting in the second half of 2007. The final release of Windows Home Server will be available as a tightly integrated hardware and software solution sold by numerous companies. "
