Long ago created a Homegroup to share resources, but never used the functions and want to delete it. The other computer no longer belongs to the old Homegroup, but the main system has problems. When I click Homegroup, it shows 3 items shared. When I uncheck and save, nothing happens. When I go to advanced sharing options and say no longer sharing, and then try again, same loop. Turned off the Homegroup services (both), but still the same loop. When I click start HOMEGROUP, shows 3 items checked, uncheck them, save and restart and the same 3 items still checked. I ask to leave the homegroup, and responds: Windows couldn't remove your computer from the Homegroup. In Advanced options turned off all sharing. Still the same loop.
Tried to see if there are any profiles in C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking
but nothing found.
Tried the troubleshooter and Windows FIX IT, can't be fixed some peer networking errors.
Windows 7 Ultimate, all current.
Do I need to turn off NETWORK DISCOVERY? And will this be a problem with McAfee network elements?
