After upgrading to Windows 11 I have a problem with the volume and brightness keyboard shortcuts not working. I figured that it was a driver from Acer. I don't remember the exact name, nor did I take any note of the hardware ID. I removed it, and the problem seemed to go away.
After a few days, Windows Update has decided to reinstall the driver and once again, the keyboard shortcuts no longer work. Even more interesting this time, I can no longer see them on the Device Manager even with "show hidden devices" on.
The driver was listed as
Acer Incorporated - HIDClass - 4/6/2017 12:00:00 AM - 22.214.171.124 on the update history. I looked up for "HIDClass" using DriverView, a third party tool and apparently it was a driver made by Microsoft, not Acer.
I tried sorting the drivers from their install/last modified date and I couldn't find anything that seems to be related and modified today, so how do I get rid of this "hidden" driver?
As a note I also used
wushowhide.diagcab after this mess happened so this doesn't happen again in the future. However I need to remove it now, somehow.
