How do I fix Magic Keyboard not working properly with my laptop and Windows?

Hi, I have bought a Magic Keyboard. But I am using laptop & Windows.

Unfortunately, my keyboard does not work properly.

On the top row, from F4 --> F118 it does nothing. And the `clear` and `=` buttons above the numeric side also does nothing.

Could you help me if it can be fixed?

I would appreciate.

Thank you.
