cursor disappears in windows 8.1

Help, I have a toshiba laptop with windows 8.1. It's also a touch screen. Ever since it updated the cursor seems to disappear and I reboot. It's there for the logon screen and the next screen, but then it disappears. I know this is a windows 81 problem because I read up on it, but nothing seems to make the cursor reappear
HELP!!!!!!!!!!!!!!
