Information
Performs networking tasks associated with configuration and maintenance of HomeGroups.
The recommended state for this setting is: 'Disabled'.
Rationale:
While resources on a domain-joined computer cannot be shared with a HomeGroup, information from the domain-joined computer can be leaked to other computers in the HomeGroup.
Solution
To establish the recommended configuration via GP, set the following UI path to: 'Disabled'.
Computer Configuration\Policies\Windows Settings\Security Settings\System Services\HomeGroup Provider
Impact:
The computer will be unable to detect other HomeGroups and any existing HomeGroup might not work properly.
