Windows 10: Volume and Brightness Key Malfunctions

When I hit a brightness or volume key on my Windows 10 keyboard, they do not work. Instead a dropdown menu window pops up or the software I am using goes completely full-screen and I can't get out of it even with the esc button which also opens a different pop-up window. If it helps, this happened a few months ago and I haven't really cared to fix it until now. I'm wondering if it happened with an update. It isn't urgent, but I'd love to be able to use these functions without going into settings every time to manually adjust them. Anything helps! Thanks ;

Changing brightness is no longer smooth with function keys on 1903

Hi, There's a the slider for brightness at the bottom of the Action Centre (build 1903).

If you'd be prepared to consider an alternative... how about smooth control of brightness using your scroll wheel?
Press a key, plus scroll, and adjust your brightness.

The key and the steps are your choice.

Oh, and it can adjust volume similarly.

Works nicely on my Lenovo Thinkpad, where the Fn key steps for brightness are a bit harsh.
