To turn on Network Discovery on a Windows PC, you can follow these methods depending on your Windows version and preference:

Using Control Panel (Windows 10/11)

1. Open Control Panel.
2. Go to Network and Internet > Network and Sharing Center.
3. Click on Change advanced sharing settings on the left.
4. Expand the network profile currently in use (Private or Public).
5. Under Network discovery , select Turn on network discovery.
6. Also, check Turn on automatic setup of network connected devices if available.
7. Click Save changes to apply

Using Windows Settings (Windows 11/10)

1. Open Settings (press Windows + i).
2. Go to Network & Internet.
3. Select your active connection (Wi-Fi or Ethernet).
4. Click on Properties.
5. Under Network profile type , choose Private Network (this automatically enables Network Discovery).
6. To disable, select Public Network instead

Using Command Prompt (Admin)

1. Open Command Prompt as Administrator.

2. Run the command to enable Network Discovery firewall rules:

   netsh advfirewall firewall set rule group="Network Discovery" new enable=Yes
   

3. To disable, run:

   netsh advfirewall firewall set rule group="Network Discovery" new enable=No
   

This method enables the necessary firewall rules for Network Discovery

Using PowerShell (Admin)

1. Open PowerShell as Administrator.

2. Enable Network Discovery with:

   Set-NetFirewallRule -DisplayGroup "Network Discovery" -Enabled True
   

3. To disable, run:

   Set-NetFirewallRule -DisplayGroup "Network Discovery" -Enabled False
   

This is an alternative command-line method

. Important: Ensure your network profile is set to Private or Home, as Network Discovery does not work on Public networks for security reasons

. Following these steps will enable your PC to see other devices on the network and be visible to them, facilitating sharing and connectivity.
