Computer Configuration\Administrative Templates\Windows Components\Home Group Description
This policy setting specifies whether users can add computers to a homegroup. By default, users can add their computer to a homegroup on a private network. If you enable this policy setting, users cannot add computers to a homegroup. This policy setting does not affect other network sharing features. If you disable or do not configure this policy setting, users can add computers to a homegroup. However, data on a domain-joined computer is not shared with the homegroup. This policy setting is not configured by default. You must restart the computer for this policy setting to take effect.
