meh when windows 10 installed it disabled it. u jus need to enable it again.hit the windows button on your keyboard to pull up the start menu. Tab down to Settings and then key down to Mouse and touchpad. Use your keyboard controls to go down to the bottom and highlight "additional mouse options," then hit enter. Go over to ELAN, then Highlight the ELAN input device. You should be able to enable or disable the device from there.
