Synaptic touchpad scroll direction not consistently reversed in Windows 10

I bought a new laptop with Windows 10 and am having issues with the Synaptic touch pad.

By default, two-finger swiping on the touchpad scrolled like a Mac (i.e. the scroll bars move against the direction your fingers move in). That's the opposite of what I like, so I went into the Synaptics ClickPad Settings (via the icon in the tray), and into the Two-Finger Scrolling properties (the properties button "conveniently" doesn't appear until you focus the row), and unticked the "Enable reverse scrolling direction" option.

This worked, except for two problems:

1. Whenever I restart, the setting reverts. It's not being saved properly.
2. In the start menu, and other metro-windows-8-tablet-tile-thingy-style places, it still scrolls in the wrong direction! (But things in desktop-land are fine.)

Any suggestions? Registry keys to tweak? Updates to install?

The machine in question is an HP Spectre x360, if that happens to matter.

Solution 1:

I finally sorted win-10 scroll direction with the Synaptics Clickpad SMB driver v 19.0.12.95 (HP Envy laptop):

• Regedit
• Find HKLM/SOFTWARE/Synaptics/SynTPEnh/ZoneConfig/Win8/2FVerticalScrolling
• Set the value of UserZoneFlags to 1 (is 65 if reverse scrolling is ticked)

I also changed same in HK Current User. Checking back it looks like the HK Current User on my laptop no longer has the setting, possibly it held the value change when I made if via the mouse settings GUI. Having reflected the change into HKLM and rebooted it's gone now, perhaps as it is using the system-wide default rather than local user preferences. Only issue with that is individual users on the PC won't be able to set and keep their own preferences. Can't recall if that was the case under Win8.1 but not too important for me.
