Volume keys on apple keyboard not working on Windows 10

Sorry about that, not sure why your response only showed up now, even though I refresh every so often.

I've no idea what an "-m qualifier" is haha. I understand your first two sentences and I understand that I need to use Brigadier in order to acquire the correct drivers instead of the "5.x.x drivers". But I have no idea how or what to download. I know of github, but I've never used it before.

If it's not too much trouble, can you give me some steps to follow in a simplified manner? I'm quite the novice! I apologize for leaving that out from my initial post. You've been very helpful! Much Appreciated!

I've no idea what a powershell is. Can you tell me step by step what I need to do? Can you please be more specific and simplify your explanations for someone who is not tech savvy.

Now that I have brigadier, does it have all the files I need? Do I need to download anything else?

What about my previous bootcamp files/drivers and the applekeyboardinstaller64, can I delete those? Or do I keep them?

I'm not sure which one you meant, so I tried both.

If I right click "Brigadier" and click run with powershell, it briefly opens powershell and then it immediately closes. There is nothing I can do.

On the other hand, if I manually open powershell and run as admin, what do I do after? Do I type the stuff above?

brigadier -m iMac19,1?

Thank you for your patience. Much Appreciated!

Thanks I downloaded Brigadier and opened the file.

The problem now is, the links you've written above, none of them seem to work.

What do I do now? Please help.

Where can I find the Model supported in package distribution file? The link doesn't work
