Turning sharing on or off
The first time you connect to a network, you'll be asked if you want to turn on sharing between PCs and connect to network devices such as printers.
Your answer automatically sets the appropriate firewall and security settings for the type of network that you connected to. You can turn sharing on or off at any time.
To turn sharing on or off
View a list of available networks by swiping in from the right edge of the screen, tapping Settings (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Settings), and then tapping or clicking the network icon (
or 
).
Press and hold or right-click the network you're connected to, then tap or click Turn sharing on or off.
Menu used to turn sharing on or offDo one of the following:
Choose Yes, turn on sharing and connect to devices for home or small office networks, or when you know and trust the people and devices on the network. This setting allows your PC to connect to devices on the network, such as printers.
Choose No, don't turn on sharing or connect to devices for networks in public places (such as coffee shops or airports), or when you don't know or trust the people and devices on the network.
Notes
Turning sharing on prepares your PC for sharing files and devices on a network. For more information about sharing with other people on your network, see Sharing files and folders on a network or a shared PC.
The network sharing setting is only available for WiFi, Ethernet, VPN (non-domain) and dial-up (non-domain) connections. It's unavailable for domain networks. On VPN or dial-up connections, you must connect to the network first, then press and hold or right-click the network name to change the network sharing setting.
Turning on sharing changes your firewall settings to allow some communication, which can be a security risk. If you know you won’t need to share files or printers, the safest choice is No, don't share or connect to devices.
Choosing No, don't turn on sharing or connect to devices blocks the following applications and services from working: PlayTo, file sharing, network discovery and automatic setup of network devices.
About network discovery
Network discovery is a setting that affects whether your computer can see (find) other computers and devices on the network and whether other computers on the network can see your computer. It's one of several settings that are turned on when you turn on network sharing. You can turn network discovery on or off independently of network sharing, but we discourage this. Here's why. If you're connected to a network in a public location and you decide to turn on network discovery but leave network sharing turned off, the network discovery setting will be on for every public network you connect to from then on. This wouldn't be safe. That's why we recommend using the network sharing setting instead.
However, if for some reason you need to turn network discovery on or off independently of the network sharing setting, here's how to do it:
Open Advanced sharing settings by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering advanced sharing in the search box, tapping or clicking Settings, and then tapping or clicking Manage advanced sharing settings.
