If you don't want the mouse sensitivity level to be the same as the touchpad, AutoSensitivity is available. After being activated automatically when Windows starts, it opens a window with which you can define the sensitivity of the mouse and the one presented by the touch panel of your laptop.
AutoSensitivity takes into account that both devices are not used in exactly the same way, so it offers you the possibility to individually adapt the degree of sensitivity of the two. Mouse movements will affect the cursor in one way and touchpad movements will affect the cursor in another way.
The sensitivity of both the mouse and the touchpad can be adjusted simply by moving the two bars located on the AutoSensitivity interface.
