Within this UI you can adjust your trackpad to a greater degree of precision than you can using the built-in windows tools.
Note: Registry usage can be harmful- be sure you have all appropriate backups before continuing! Once enabled I was able to fine-tune the trackpad settings to be more bearable. Luckily, after days of searching the web and testing ideas I finally found an extremely easy way to make my (and hopefully your) touchpad work better than ever, with gestures and even smooth scrolling. In investigating this further I found that the Synaptics driver hides the 'advanced settings' from windows 10 users for some inexplicable reason. Synaptics wasnt able to update the touchpad drivers to work with the new Windows again, so some people cant even scroll using their touchpad and the cursor is stuttering over the screen.
While examining specific trackpad details, I found that I have a Synaptics LuxPad V1.3 device that communicates using an SMB port (whatever that is!) I was working on a ZBook G3 the other day and ran into an infuriating issue with its Synaptics Touch Pad: The touch sensitivity out-of-the-box was set so high that when I slowly moved the cursor it would get jittery and not respond.
