Brightness controls not working (Windows 10)

This is what I see in Device Manager:

OK, I tried resetting the SMC and the NVRAM. The brightness function keys are still not working.

I looked at the Windows update history -- Maybe I was wrong about the problem starting when the drivers were updated. It may be this problem started when the AMD Installer software updated.

Here's the most recent driver update for the keyboard and the display:

OK, I managed to uninstall the Apple keyboard driver and reinstall it as you suggested above. However, the brightness keys still aren't working.

Anyway, thanks for all your help, Loner T. As always, it is much appreciated!

I checked the services -- there are no Apple services stopped.

Here's what's under HID -- There is an Apple Keyboard listed, is that what you're referring to?

Here's the entry for the AMD Installer software:

Here's the version of the software I'm running:

More driver settings:

The software refuses to perform the update. Here's the message I get:

When I try to uninstall the Apple keyboard driver, I get this error:

Yes, the brightness keys work fine in OS X.
