Synaptics touchpad - scrolling issues after Win7 to Win10 upgrade

Well, there's more to report.... and possibly progress, although with a slight twist.

A conversation in another thread with @Try3 led me to a guide he had produced here about searching for drivers (in this case for a touchpad) using the Hardware ID.

So I found the ID for my touchpad and went looking. I couldn't find anything through a search on the Synaptics site. But the search led me to one or two download sites (filehippo was the one I went to) which apparently offered drivers for this touchpad. I downloaded v.19.2.17.59 - and installed it.

To my slight surprise, and great relief, the touchpad works with this more recent driver. The good news is - it now also scrolls properly in the Win10 Start Menu and in Settings pages, and in the MS Store - all the UWP-designed apps where scrolling didn't previously work.

The weird news is that in Device Manager the touchpad is now listed as a Dell touchpad. The driver still shows as manufactured by Synaptics. But the Synaptics tab for additional settings (with all the options listed in my earlier post #9) has gone.

I suppose if I had followed @Bastet 's advice to try the Precision touchpad driver, something similar would have happened?

Anyway - I suppose this is a step forward, in that the scrolling problem is resolved. No help from either the Samsung support or Synaptics websites, but ultimately this forum has both identified the cause of the problem (UWP apps - thanks @jbcarreon123 ) and suggested a solution (thanks @Try3 ) albeit carrying a Dell label.

 

Latest Synaptics Touchpad Driver for Windows 10


After updating from b. 10240 to 10586.3 ( W 10 x64), Windows installed an older version of Synaptics 19.0.15.2, before I had 19.0.19.1.
Also now, in Device Manager, it's listed under PS/2 Port touchpad, before it was SmBus.
Windows Update does no longer provide 19.0.19.1 driver, Why??
What are the recommended steps to get installed manually the latest Synaptics driver because with the currently installed driver, mouse scrolling does not work for Start menu - All apps, with 19.0.19.1 it used to work.
Also what is the name of the x64 .inf to use for update synSmbDrv.inf or SynPD.inf??
Thank you.
