How to hide or disable "allow PC to be discoverable on this network"?

Question

How to always hide or disable "allow PC to be discoverable on this network"? I've created a scheduled task to take care of that which means this prompt is not only unnecessary it's also a security risk if accidentally clicked.

Solution

You should be able to prevent this dialog from showing by adding the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Network\NewNetworkWindowOff

Open regedit.exe, navigate to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Network, and add a new key by the name of NewNetworkWindowOff.
