"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This is for Firewall profiles and is used by Network location awareness (NLA).  You can configure your firewall to allow file sharing on a home and work network, RDP on a work network, and be completely closed on a public network.  You might want to review this blog:

A home network and office network are trusted networks for trusted locations and users.
Network discovery is turned ON by default.
The only difference is that you can only use a HomeGroup with a home network.

A public network is for public places (coffee shops, hotels, airports). It's designed to keep your computer invisible to other computers and to help protect your computer from malware on the Internet.
Network discovery is turned OFF by default.
HomeGroup is not available.
