Windows10 - synaptics forgets settings

Instead of reinstalling drivers you can simply modify a variable in regedit.

Change the value of DeleteUserSettingOnUpgrade to 0 from \HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Install

After restarting your settings will be kept.

Had the exact same problem. Fixed by re-installing the driver. I found the 19.0.12.95 driver on HP support website. Put 15-n207sa as computer model that will bring put the right driver.

So i found out that drivers i downloaded had clickpad software, i downloaded some with touchpad software, drivers itself are probably same, but software is older synaptics one and it works and scrolls the way i like it :)

EDIT: i have used https://catalog.update.microsoft.com/v7 in internet explorer and downloaded latest synaptics drivers that had touchpad in name, also please check that you are downloading amd64 version for x64 systems.
