The three network profiles in Windows 10 are:

• Private: Computers on a private network can belong to a home group. Network discovery is turned on for private networks, which allows you to see other computers and devices on the network.
• Public: Designed to keep your computer from being visible to other computers around you and to help protect your computer from any malicious software from the Internet.
• Domain: It belongs to enterprise network. It’s controlled by network admin and can’t be selected and changed locally.
