Clicking Frustration

So, one of the most frustrating things that I've encountered on my district issued laptop is when the mouse randomly decides which button is the "primary" button (basically the left click becomes the right click and vice versa). I have several teachers that couldn't figure out how to fix it and just "got used to it" as they've said, but this isn't something you have to live with! I've made a short tutorial on how to fix this when it happens. There may be an easier way; if there is, let me know by commenting below!
