HP Elitebook 850 G6 Touchpad breakdown epidemic

HP Recommended
HP Elitebook 850 G6
Microsoft Windows 10 (64-bit)

This seems to be a problem many other people in the forum are having, but it's unclear if HP is aware. After windows installed some intel drivers on friday, trackpads on the above model suddenly stop working right. It's like windows lost it's connection to them, as the sensitivity is suddenly cranked to a completely unusable level (users even breath on the touchpad, the mouse flies to the corner of the screen). Adjusting touchpad sensitivity in the Settings does nothing. When we roll back the driver, no change. When we uninstall the driver completely the touchpad will work fine, until windows stuffs the Symantics update back in. Only fix I could make actually stick was to switch to the generic PS/2 mouse compatable drivers built into windows, but for some reason then the Intel managment engine freaks out and kick out errors on reboot, and the speakers become completely unreachable via device manager. Even installing HP Support Assistant to update everything fails. We have nothing but HP Elitebooks for the most part, and this is going to become a very busy christmas week for my poor IT department. Is there any fix even in the works?

There are a couple of other threads with the solution.


I do wander how it is possible that the issue is still not resolved with HP.
