See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=78918. Someone reported a similar problem, which I was unable to reproduce (on a Lenovo laptop with a touchpad). It then turned out that the OP fixed the problem by reinstalling Windows. I can only repeat that I cannot reproduce this, and ask you to examine your Windows settings and installed software for some factors which could explain what you see. If/when we understand what causes this, we could discuss possible solutions. Btw, I'm not sure I understand completely which touchpad gestures don't register. So please describe in details the gestures which do not register: how exactly do you perform them on the laptop. I suggest that you write these details to 78...@debbugs.gnu.org, so that we could discuss the problem there.
