Answer to: How to reinstall touch screen driver? My touch screen stopped working.Hehehehehe!!! Go to CONTROL PANEL, click Mouse, under Mouse properties click Hardware, check on the devices - you will see the items in the available options. double click on the Touch stuff to see its Properties. Go to Driver [there you will see options like Driver Details, Update Driver, Roll back Driver etc..]Just click on the Roll back Driver, wait for some second then click OK and that's all. Soft Touch resumes.
