Windows 10 Trackpad Issue Resolved

For Windows 10 users 

Start Menu > Settings > Devices > Mouse and Touchpad - scroll to bottom > Additional Mouse Options

Hardware "HID Compliant Mouse" > properties > change settings

I have this (Windows Driver) disabled. From the downloads page for the drivers for Inspiron 7548 you'll get the dell updates software or proprietary driver itself but its called ETDWareUsb********.

The thing is that both drivers are trying to handle the same device at the same time.

I think the Windows 10 trackpad driver works fine but you should only have one or the other.

Having now used the latter its much more accurate and makes this trackpad turn from nightmare into something nice.
