I have been using windows 10 for a week now without any problems. Today windows 10 installed "eGalaxTouch - Other hardware - USB Touchscreen Controller(A103)" through windows update. It has turned my touch screen into a mouse.
Edit: By acting like a mouse I mean that, I can not use touch gestures, option to open on-screen keyboard has disappeared, and scrolling the web browser's page results in selection of text instead of scrolling. Also it lists under 'Mice and other pointing devices' in the device manager.
Edit 2: Also touchscreen driver is not listed on my laptop's (HP ENVY TouchSmart 15-j137tx ) website.
This driver does not show in 'installed updates', so I can't uninstall it. I tried deleting the driver from device manager but it does not work.
How do I revert to older touchscreen driver?
