Got it working on an old 2007 laptop running 10. This is what I did, Device Manager, expand' Mice and other pointing devices', right clicked Synaptic PS/2 Port TouchPad and uninstalled including the drivers. Rebooted and now I can one-finger scroll again. The generic driver works for Synaptic touchpad. Have a mouse handy if you're going to try it and if your touchpad is Synaptic.
