I managed to get the brightness on my laptop (MSI gp72 2qe Leopard Pro) and tried to enable the brightness keys with this Method.
My keys are handled via ACPI and the code for brightness up is _QB7(fn+up arrow) and for brightness down _QB8(fn+down arrow).

The keys are working but they are changing the brightness 3 times which you can see in the video in the attachments.

I applied this patch here:
Code:
into method label _QB7 replace_content
begin
// Brightness Down\n
    Notify(\_SB.PCI0.LPCB.PS2K, 0x0405)\n
end;
into method label _QB8 replace_content
begin
// Brightness Up\n
    Notify(\_SB.PCI0.LPCB.PS2K, 0x0406)\n
end;

How can I fix this?

What do you mean by "brightness the times"?
What do you mean by "video in the attachments"? (there is no attached video).

In the future, please do not attach the entire EFI folder. Attach only EFI/Clover without themes, as per FAQ:

It's same with my MSI GP62MVR 6RF, the brightness change 3 times with one key click. Alternative solution is using F14/F15 button (scroll lock/pause break in my keyboard layout) to change the brightness.

Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.

ACPI not patched correctly. No evidence of "OS Check Fix" patch.

I have moved the kexts and added the OS Check Fix(Win 10).
Which Windows Version should I use for the OS Check Fix?
Or should I use all versions which were available (Linux,Windows)?
