Just to clarify, windows does not show a touchpad device in settings. The manual says to click the three icons on the taskbar wifi, speakers, battery icon then click the "wheel" for all settings. This brings up the Bluetooth & Devices window and there's nothing available for touchpad. The only "input" device is a bluetooth mouse I added. Again, touchpad works fine, but it doesn't appear to be configurable.

Here's the driver loaded for the touchpad. I tried uninstalling the device, then rescanned for new devices which reloaded the microsoft driver. When I checked for available acer drivers from the acer support site, no touchpad driver was listed amongst the many other drivers. Possibly this is "normal" for this laptop in windows at this point and acer doesn't actually supply a touchpad driver.

That would be a lot of changes to make! I hesitate to do this as the touchpad does work OK, just can't access the settings. Thank you though.
