I searched high and low for this.
There doesn't seem to be a way to change a customer's network profile from public to private. The laptop is connected to the enterprise network and I don't know anything about it's configuration.
What can I do / should I ask them to do in order to be able to change the profile?
I used this tutorial to try and change it, but neither of them worked because some exe's aren't available in Win 8 home. The registry tweak did change the name displayed in network and charing center but didn't flip over the connected network profile (sharing settings).
Even when I go to the folder network locations, a yellow bar on the top appears telling me that sharing is disabled. When I go ahead and click that a popup informs me that I need to change the profile to private. When I choose to change the network profile there, nothing happens.
