Head to the same Additional Mouse Options window mentioned above and look for an extra tab with touchpad settings-often, you'll find more options hidden there. If your laptop falls into this category, you may have other settings hidden in Windows that offer more control. Many modern laptops use touchpads designed with Microsoft's drivers in mind, but older models might still use drivers from manufacturers like Elan or Synaptics.
Head to Settings > Devices > Mouse > Additional Mouse Options, and you can also try enabling or disabling Enhance Pointer Precision. Multi-touch gestures could also be causing you grief, so turn those off if you find you keep invoking them accidentally. In addition, you might want to turn off the tap-to-click features, or the lower-right-corner feature that comes enabled by default.
Head to Settings > Devices > Touchpad and change the touchpad sensitivity. Not all touchpads are created equal, but there's a good chance your laptop's drivers will let you adjust a few settings, allowing you to customize how your touchpad responds to your movements.
