Actually there are many ways to fix this problem and getting rid of Homegroups isn't one of them.
This can be one of two problems.
1. Click Start. Search for run and press enter. In the field, type regedit
and press OK.
2. In the registry, navigate to the following key.
3. In the right pane, right-click on “DisabledComponents
” and select modify. In the value data field, type “0″
(without quotations) and press OK. If the value was set to ``FF``, it was turned off.
4. Reboot your computer and it should work. It did for me. Or try this.... Go to
C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking and delete all of the files in this folder. Now restart the computer.
