When you try to remove a PC from the HomeGroup on Windows 7, you might receive error.

When you run the troubleshooter, you might receive the following problem:

Problems found: Peer Networking Grouping service isn’t running

To solve this error, please do the following:

Delete the file:

idstore.sst

that is located in the following path:

%SystemRoot%\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking

When you paste this line in the RUN windows you might receive the Access Denied error.

In that case just copy: %SystemRoot%\serviceProfiles\ in the RUN prompt and try to open the Local Service folder again. You will receive the following message:

You don’t currently have permission to access this folder (UAC). Click Continue and then navigate to the PeerNetworking folder. (Have in mind that AppData is a hidden folder)

Open RUN prompt again and type the following services.msc

Stop the HomeGroupProvider service and restart.
