There's sc[1] on Windows for this, though many services can do it themselves, eg

    myservice.exe /install

Of course, the application must support the service interface[2] to do this, which is like providing the .service file for systemd.

The key difference is that it's built into the application[3] in Windows, not external like with systemd, which has pros and cons.
