HomeGroup - Windows 7 - 70-680

A homegroup is a group of computers on a home network that can share files and printers. Using a homegroup makes sharing easier. You can share pictures, music, videos, documents, and printers with other people in your homegroup. Other people can't change the files that you share unless you give them permission to do so. You can help protect your homegroup with a password, which you can change at any time.
