Windows 10: Mouse scroll setting keeps changing

How do I change scroll direction of a mouse NOT listed under Mice?

Thanks; yes, those are great directions and did work to change the direction of the wired mouse that came with the computer.

I need the mouse to appear on the list of mice in order to complete this sequence.
