Control file and printer sharing on your home network — and turn it off cleanly on public Wi-Fi.
Windows' sharing settings — who can see your PC, whether the Public folder is available, whether SMB1 is on — are spread across several control-panel pages. Network Sharing consolidates them into one page, with three quick-setup presets and a full list of fine-grained toggles.
Windows tags every network you join as either Private (home, trusted) or Public (coffee shop, airport, hotel). Sharing settings are stricter on Public networks by default, which is a good thing. You can see the current profile at the top of the page and change it with the dropdown.
One click turns on file sharing, network discovery, and the Public folder, disables SMB1, and keeps password protection on. The sensible default for a home PC.
Turns off every form of sharing and discovery. Your PC becomes invisible to other devices on the network. Use this when connecting to untrusted Wi-Fi.
Enables SMB1 (the ancient file-sharing protocol) to talk to older network-attached storage and network printers that can't speak modern SMB. Only use on a fully trusted home network — SMB1 has known security weaknesses.
