At Microsoft we believe that the power of technology can accelerate change and help to solve some of society's most pressing issues.

Windows® 7 has been designed to make your PC simpler, and to make the things you do every day easier. To celebrate the launch of the Windows 7 operating system, we want to discover some creative ways that a PC running Windows can help an organization to make an ever greater impact in their community.

Participating in this competition is easy. Submit a short video at www.7waystochangetheworld.com explaining or illustrating how you would use Windows 7 to help a community organization. The 7 people with the best submissions, as chosen by our judges, will each win a new PC running Windows 7. And each winner's chosen (eligible) community organization will receive a $7,000 grant.

We plan to share all the submissions online, providing a great resource for nonprofits and community organizations to find out how technology can help support their local work.
