Same issue here.  For me it was a Intel Serial IO Driver?? from the pc driver's website. This is an hp-pavilion, I looked the site using the part number in the HP support page and got to the drivers for the exact model. There I started installing all drivers until the Serial IO Driver. It says nothing about touchscreen so you have to guess. It was an Input/Output driver missing.

At first the touchscreen responded to touch.

I updated Windows yesterday morning.

The touchscreen did not respond to touch.

I ran HP Support Assistant/HP Updates.

The touchscreen responded to touch.

Last night there were additional Windows updates.

The touchscreen did not respond to touch.

I ran HP Support Assistant/HP Updates.

There were no updates available.

The touchscreen still does not respond to touch.

 

Device Manager/Human Interface Devices does not list a touch device.

 

What do I need to do to get my touchscreen running again?

The UEFI tool was missing after win 10 install. It needed to be installed from HP drivers site for this pc.
