- The driver is a mouse emulation driver. If your USB interface touch device is projected capacitive type and Windows version is Windows 7 or later, we suggest you do not install this driver. There is a HID touch digitizer build-in driver in Windows 7 or later.

This package supports the following driver models:TouchKit USB Controller for TouchScreen.
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?

Driver rollback from the device manager worked. Older microsoft HID-complient drivers were installed and everything is working perfectly now.
Edit: The screenshot below was taken after the rollback. People facing the same problem will need to rollback the touchscreen driver listed under 'Mice and other pointing devices'.

I had the same issue as nonameswereavailable. The HID-compliant touch screen driver was hidden and apparently was disconnected from the computer after the update, you could only see it from device manager >> view hidden devices. There was no rollback available (since it was disconnected, I think).
I ended up restoring my system to before the update happened, and then followed this to stop installing drivers automatically, and this to stop updating automatically too, which might be a bad idea. We'll see. Battlefield 1 crack only.

In my case the rollback option was disabled. I was able to restore the old (and correct) behavior by using the option
'Update Driver software -> Browse my computer for driver -> Let me pick from a list -> USB Input Device'
