HP AIO 27-a010 Touch Function GONE - Driver update failing due to runtime error

[JLick]

Windows prompted me to update a few days ago, since the update I had lost my touch function. The driver is gone, no touch device shows in Device Manager anymore, the touch function also does not work in the bios. I have since factory reset the PC which has not helped. Can someone please tell me this is not a hardware issue as it was working just fine, since purchase over a year ago, up until that Windows Update.

Please download and re-install the following Intel HD Graphics Driver :

Thanks for this suggestion.  I have downloaded and installed sp85346.exe. Restarted PC and a dialogue finished testing/installing. After, still no driver listed in device manager, nor any pen/touch info recognized. Issue still persists.

Please try the following fix

Otherwise roll back to Restore point or uninstall updates few days ago.

Regards.

Thanks again for the reply. I went through that whole thread before you replied, trying all the fixes. Nothing has worked.

EDIT: I cannot rollback a driver for a item not listed in the device manager. I also tried factory resetting PC and reinstalling windows as was also recommended and neither worked. So no restore point. No visible driver (Yes, I have enabled "HIDDEN DEVICES")

The touch screen does not work in bios. The fix for the driver from HP's driver site says runtime error everytime it searches for a touch device, and crashes. I've already updated all my visual studio. Seems MicroSoft and HP are playing the blame game on who is at fault and neither wants to take responsibility. I know I'm not the only one with this issue after days of research. And I also know this is not user-error. It's been beyond frustrating that the selling feature of my PC is just broken. $1000 anchor is how it feels right about now.

I now have the exact same issue. Touch just stopped working. Tried just about every suggestion out there,  The BIOS is not reporting it as a Touch device so everything after that is not seeing it.  There are several streams of the same topic going on in HP Support.

I am having the same problem with my Hp 27-a010 all in one. The touch screen is not working and the bios is saying it is not a touch screen. Anyone have a solution?

Thumb`S Up for Touch Screen all in one computer, as you might only us without Touchscreen

Are there someone, how might have the solotion, how i can get my HID Touch screen driver back?

All do i have to bring my computer back to the shop, and recommend others not to purchase those kind of computers to anyone.
