Lenovo Yoga 11e Touchscreen Driver Missing

I don't know what caused it, may the Driver update program, but I no longer have a Touchscreen driver. I contacted Lenovo and they told me to reset to a previous version of Windows. No luck. They told me to reset the entire computer, I did, but still no Touchscreen driver. The computer was not dropped or damaged. I cannot find how to add a driver, just how to update one. I would appreciate any help.

Thanks

Thanks for the quick response. I used the link which took me to Lenovo System Update: Update Drivers, BIOS and Applications which I guess is what you were recommending. I downloaded and ran System Update, which did not solve the problem. Someone from Lenovo told me my touchscreen may be broken. Is there a way to check to see if it is?
