Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Install
Note this is LOCAL MACHINE, not CURRENT USER.
Look for a key in that Install folder called DeleteUserSettingsOnUpgrade
Double click and change the value to 0.
Now go back to the Synaptics control panel, set everything how you like, and reboot.
