Turning off Windows 11 sharing settings can stop other devices from finding your PC or using files, folders, and printers shared from it. It does not, by itself, delete your files or remove each folder’s individual share. The effect depends on which control you change: Network discovery, File and printer sharing, the network profile, or password-protected sharing.
What each setting changes
These controls affect different parts of local-network sharing. Network discovery affects whether other devices can find your PC through Windows network browsing. File and printer sharing affects resources hosted by the PC. The network profile sets whether Windows treats the connected network as trusted for discovery and sharing. Password-protected sharing controls a separate access-protection choice.
| Control | Where Microsoft places it | What happens when disabled or changed |
|---|---|---|
| Network discovery | Private networks | Other devices may not find the PC in Windows network browsing. Microsoft says discovery must be on to see devices on the network that are sharing files. Microsoft Support |
| File and printer sharing | Private networks | The PC’s hosted folder and printer sharing is interrupted, so clients may no longer be able to use those shared resources. Microsoft Support |
| Network profile | Windows network settings | Public hides the PC from other devices and prevents using it for file and printer sharing; Private permits discoverability and sharing. Use Private only on a network whose users and devices you trust. Microsoft Support |
| Password-protected sharing | All Networks | Changes password protection for network sharing. It is separate from discovery and file/printer sharing, not a prerequisite for turning either of those controls off. Microsoft Support |
What breaks when Network discovery is off?
Network browsing can fail: for example, File Explorer’s Network view may show “Network discovery is turned off…” and devices that share files may not appear there. This is a discoverability problem; it does not mean Windows erased the shared files or deleted the share configuration. Microsoft’s guidance is to turn discovery on when you need to see devices sharing files on the network. Microsoft’s file-sharing guidance
What breaks when File and printer sharing is off?
The computer can no longer reliably serve its shared folders or printers to other devices on the local network. Microsoft’s folder-sharing troubleshooting steps call for enabling File and printer sharing under Private networks; its printer-sharing instructions also require sharing to be enabled. This setting concerns sharing hosted on this PC, rather than deleting the source files or uninstalling a printer. Folder-sharing guidance · Printer-sharing guidance

What changes with a Public network profile?
Windows treats Public as a less-trusted network context: Microsoft says a Public profile hides the PC from other devices and does not allow using the PC for file and printer sharing. A Private profile permits discovery and sharing, but should be used only where you know and trust the people and devices on the network. Do not switch an unfamiliar public Wi-Fi connection to Private just to make sharing work. Microsoft’s network settings guidance
Does turning off sharing delete a folder share?
No. Disabling a broad sharing control interrupts network access; removing a particular share is a separate action. To stop sharing a specific file or folder, Microsoft documents this File Explorer path: right-click or select the item, choose Give access to, then Remove access. The shared data remains on the PC unless you delete it separately. Microsoft Support

What password-protected sharing does—and does not do
Password-protected sharing appears under All Networks, separately from Network discovery and File and printer sharing, which Microsoft addresses under Private networks in its troubleshooting steps. Turning it off changes the password-protection arrangement for network sharing; it is not required just to disable discovery or sharing. Microsoft lists disabling it as one troubleshooting step, not a universal prerequisite. Consider the access implications before changing it.

A printer that vanishes from another PC is not necessarily broken. For network printer sharing, Microsoft says the printer must be installed and working on the primary Windows device, the host must be powered on and connected to the network, and printer sharing must be enabled. Network discovery and the network profile can also affect whether clients can find the host. Microsoft Support

Restore sharing or diagnose a failure
- Check that the computers are connected to the same network.
- On a network you trust, confirm that the Windows connection uses the Private profile; do not use Private for an unfamiliar public network.
- Open Windows Settings and go to Network & internet, select the active Wi-Fi or Ethernet connection, and verify its network profile. Windows labels can vary by update.
- In Advanced sharing settings, under Private networks, enable Network discovery and File and printer sharing if you want this PC to be discoverable and host shares.
- If network browsing still fails, Microsoft’s troubleshooting guidance says to check whether Function Discovery Provider Host, Function Discovery Resource Publication, SSDP Discovery, and UPnP Device Host are set to start automatically. Treat this as a troubleshooting branch, not a requirement to change all four services in every case. Microsoft Support
- For a printer, verify its setup and sharing on the primary PC, then confirm that PC remains powered on and network-connected.
