On Windows, services use this API: https://learn.microsoft.com/en-us/windows/win32/services/services https://learn.microsoft.com/en-us/windows/win32/services/ser... Services are executables, but they have dedicated entrypoints/"signals" for interaction with the service manager. That means you can't point a service at a batch file or powershell script, because those applications don't have the symbols to respond to the signalling from Windows.
