HomeGroup makes it easy to share pictures, music, documents, videos, and printers with other people on your home network. When you set up a computer with this version of Windows, a homegroup is created automatically. But you can also create a homegroup by following these steps:
Open HomeGroup by clicking the Start button , clicking Control Panel, typing homegroup in the search box, and then clicking HomeGroup.
On the Share with other home computers running Windows 7 page, click Create a homegroup, and then follow the instructions.
If a homegroup already exists on your network, Windows will ask if you would like to join it instead of creating a new one.
If you don't have a home network, you'll need to set one up before creating a homegroup. For more information, see Setting up a home network in Windows 7.
If your computer belongs to a domain, you can join a homegroup but you can't create one. You can access files and resources on other homegroup computers, but you can't share your own files and resources with the homegroup.
After you create a homegroup, you must add other computers to it so that you can access shared libraries and printers. For more information, see Add computers to a homegroup.
