I have no idea what your question is. All we know is that you have a Windows Service and a second Windows Forms application that talks to it? So what's the problem?

Look for interactive windows service...

The usual way of doing this is for your service to listen for connections on a TCP/IP port and the client apps connect to that port (and the connection is accepted on a different port server-side so it can remain open for new connections). Once the client and server are connected they can exchange info between themselves as needed.

You need to establish create full-duplex communication with the service, to receive push notification (updates) from the service. For that purpose, the service should have appropriate client-layer protocol. It looks like you need to implement publisher-subscriber model: first, your client application sends request to the service, and the service replies. To subscribe, the client part sends appropriate command to the service, with connection information; the service connects to client part (this particular client) and start sending notifications as new data is ready. Please see:
Duplex (telecommunications) — Wikipedia, the free encyclopedia[^],
Application layer — Wikipedia, the free encyclopedia[^],
Push technology — Wikipedia, the free encyclopedia[^],
see also my past answer: Application 'dashboard' for website accounts[^].

You can implement it on different levels, from raw sockets to WCF.
