I hope this will help your concern.
Hi,
Scrolling or any multiple-finger touchpad actions are not working on my computer since today. Before that, everything was fine. I have Windows 10 (since July).
My computer ( Lenovo Z50-70, if that's any helpful) does not recognize any touchpad device, as you can see on the picture.
