Port 4664 is primarily associated with Google Desktop Search, an application developed by Google to index and enable quick search functionality over a user's local files and emails. This port facilitates communication and management of search queries between the user interface and the local indexing service. Though Google Desktop was discontinued, references to this port can still be found in legacy environments or within archived software setups.

Which one is on your host

ask the machine, not the registry

The registry says what 4664 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 ':4664\b'
macos: lsof -nP -iTCP:4664 -sTCP:LISTEN
windows: netstat -ano | findstr :4664

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 3 entries above.

A port number is not a service. Anything may listen on 4664 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
