While creating a new Network on your Windows 7 computer, you are asked if you would like to treat the connection as a Home network, Work network or a Public network.
You are also given the option to check a box which says: Treat all future networks that I connect to as public, and don’t ask me again.
If you have checked this box, then in future, you may be unable to change or set your network connection location when attempting to connect to a network.
The location associated to the network connection may not be a clickable link and the Windows 7 Network connections will be stuck in Public mode.
If you face this problem, you can download and apply Fix It from KB2578723. This fix it will reset the settings, rectify the problem and make the network connections link clickable..
