Adding Octave 4 (CLI) to system path variable (Windows 10)

I installed Octave 4 (from here) which has both a GUI and a CLI.
However, Octave doesn't seem to be added to the PATH variable, so typing octave or octave-cli into the command line doesn't do anything.
Is there a way to fix that (without adding all the other executables in Octave's bin directory to PATH as well)?

I use Windows 10.

You don't add .exe files to the PATH, you add directories.

So you should add C:\Program Files\Octave\bin (or whatever your installation is) to PATH.

See How do I set system environment variables in Windows 10? for instructions on how to modify envronment variables (like PATH).
