Port 4672 is commonly associated with eMule peer-to-peer (P2P) file-sharing traffic, particularly using the UDP protocol for network communication purposes such as server discovery, peer discovery, and control messages within the eDonkey network. Although primarily unofficial, it has become a de facto standard port for many eMule users to facilitate smoother operation and better connectivity across firewalls and NAT devices.

Which one is on your host

ask the machine, not the registry

The registry says what 4672 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

linux
ss -ltnp | grep ':4672\b'
macos
lsof -nP -iTCP:4672 -sTCP:LISTEN
windows
netstat -ano | findstr :4672

On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.

A port number is not a service. Anything may listen on 4672 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
