Typically, a homegroup is created automatically when you set up a computer with this version of Windows, but there are several things that could prevent you from creating one.
To diagnose and fix common problems with creating a homegroup, first try running a Fix It wizard.
Click this button:
Fix this problem
Click Run, and then follow the steps in the wizard.
If running the Fix It wizard doesn't solve the problem, refer to the following list:
A homegroup already exists on the network. If a homegroup already exists, you will be asked to join it.
HomeGroup is available in all editions of Windows 7. In Windows 7 Starter and Windows 7 Home Basic, you can join a homegroup, but you can’t create one.
You might not be connected to a network. To connect to a wireless network, follow these steps:
After you've connected to the network, you can join a homegroup if one exists on your network.
Your network location might not be set to Home. HomeGroup only works on home networks. To change your network location, follow these steps:
Open Network and Sharing Center by clicking the Start button , and then clicking Control Panel. In the search box, type network, and then click Network and Sharing Center.
Click Work network or Public network, and then click Home network.
If you are on a domain network, your system administrator might have turned off HomeGroup completely, so you won't be able to join a homegroup.
One or more required services are not running. The Peer Networking Grouping and HomeGroup Provider services must both be running. Here's how to check this:
Open Administrative Tools by clicking the Start button , and then clicking Control Panel. In the search box, type administrative tools, and then click Administrative Tools.
If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
In the Status column, next to the Peer Networking Grouping and HomeGroup Provider services, you should see the word Started. If you don't see this, double‑click the name of the service, and then click Start.
