This will be a short one, we had an issue where the keyboard stopped working on reboot. The keyboard device was having an upperfilter driver added to it. Removing the extra entry and then rescanning for devices caused it to work again.
As I searched for solutions, I noticed that each guid in HKLM\SYSTEM\CurrentControlSet\Control\Class\ covered an individual device in device manager. I’ve pulled PID & VID from device manager before and I started to think maybe the newer device managers also show this class id link as well.
And it does. That could be handy to know.
