Please help

Hello Riot and fellow players so lately I've been playing LoL on my laptop and the trackpad isn't working after I installed windows 10 on it, before I installed windows 10 my trackpad was fine and no problems. So now when I go in game you know the little finger that becomes your curser? Sometimes it gets stuck, so instead of my swiping once to move it I have to swipe any direction like 3+ times otherwise it will be stuck like that forever and it happens randomly like every 20 seconds...so if I dive or facecheck Im fucked lol. Please guys help me, some people say when you install windows 10 it messes up your trackpad data or whatever, do I have to go and connect a mouse with my laptop? Because I really don't want to have to do that... whoever helps gets a mystery ward
