    Does this answer your question? [How can I run an EXE program from a Windows Service using C#?](https://stackoverflow.com/questions/5307968/how-can-i-run-an-exe-program-from-a-windows-service-using-c) – gunr2171 May 10 '22 at 20:46

    I think you need to read the first answer on that linked question. The answer is you cannot do what you're asking. You need to make a service that can be communicated with, and a client app. Two separate executables. – Logarr May 10 '22 at 21:07

Services do not display a user interface directly due to Session 0 isolation. So you'll need to rethink with a client-server-style separation of service processing from user interface.

The user-mode UI process will start when the user logs in and remain largely idle/hidden. It will establish an inter-process communication connection to the service and await orders in client-server fashion. If the server wants to "push" some kind of an alert to the client, it does so by notifying the user-mode application to display the user interface on its behalf.
