Question Touchscreen not working on HP Envy TouchSmart under Windows 10 ?

[KLund1]

Hi All,
I am working with a HP Envy TouchSmart 4-1115dx.
It has had an upgrade to an SSD so the recovery partition is gone. It has Windows 10 updated to 22H2 but the touchscreen didn't work even before that update.
I was assured that the touchscreen used to work until the previous owner upgraded to Windows 10.

There appears to be no physical damage that would prevent touch from working.
Device Manager shows no ' ! ' anywhere but the touch screen does not work.

If I recall, these models used to have Windows 7 with the touchscreen working. Maybe it was win8. That was a while ago.
What can be done to get the touchscreen working again?
Thoughts, suggestions, ideas, etc .... ????
Thanks

sound like it doesn't have windows 10 driver.

Thanks
I do not know what driver to get.
As above, Device Manager shows no " ! " yellow or red.
Win10 does not know about the touch screen.
What driver do I need to use?
