Windows built-in brightness adjustment does not match

[cetemadi]

Windows built-in brightness adjustment does not match Twinkle Tray's or is essentially non-functional. When using the brightness keys on my keyboard, I see the windows brightness overlay, but brightness is not changed and it doesn't match the twinkle tray levels either.

Would be great if this could be unified with TwinkleTray's levels, or if the built-in brightness keys/controls could be added as hotkeys or secondary input.
