Group Policy Setting of the Week 41 – Prevent the computer from joining a Homegroup

Last week I talked about the “Remove Homegroup link from the Start Menu” option that removed removed the links from the start menu to the Homegroup option without it being disabled. However the setting by itself does not stop a computer from joining a homegroup. So this weeks setting is of course called “Prevent the computer from joining a Homegroup” and is a per computer setting that can be found under Computer Configuration > Administrative Templates > Windows Components > Homegroup. 


Note: Unlike the name suggests if you enable this setting and the computer is already joined then the next time it is reboot it will not connect the homegroup it is already a member (See image below). Therefore I recommend you implement this in conjunction with the “Remove Homegroup link form the Start Menu” setting so as to not confuse the users by allow them access to something that will not work.

Also note that if you were to then remove of disable the “Disable Homegroup” policy then that computer would also no longer be a member of that homegroup anymore.

  1. I’m just wondering what if any security risk is there allowing a user to joing a Homegroup. I’m trying to see the rationale behind this policy.

    1. Not a lot… the rational for disabling this would be to prevent users from sharing information on their home networks… however its not as if there is not a 100 other ways to do this… really the only reason to do this would be to disable the new feautre so that users dont ask for support when setting up a homegroup…
