How do I create a homegroup?
You cannot create a homegroup if your computer is joined to a domain. In addition, it must be running at least Windows 7 Home Premium. During network setup, choose Home network from the list of network locations. The Create a HomeGroup wizard will start automatically, guiding you through choosing what you want to share and generating a strong password that is required to join other computers to the homegroup. If you’ve already configured the network connection, you can create a homegroup later by using the Network and Sharing Center.
