I updated an old computer from 7 to 10 and I got to like 10. But then after an update my touch pad quit working. Fortunately this laptop still had a "joystick" or whatever it's real name is in the keypad between the g and h keys. Using that I googled the problem and found a fix that involved downloading and installing an older version of the touch pad driver, and then editing the registry (regedit) to prevent it from updating in the future.

I'm glad that fixed it but I learned a lot more about operating systems than I want to know.
