Media Keys in Windows 10

What is the point of having dedicated Media keys if you have to use a key combination to use them?
I have the Corsair Raptor K50 and the media keys do absolutely nothing unless I also hold the windows key.
Using Groove, iTunes and Foobar (it does however work without the windows key with Google Play Music).
Same thing happens with a terrible old Dell keyboard I have.
Is there a reason for this? Can I turn it off? It’s terrible.

Remap them. That's what I had to do.

How exactly would I go about doing that?

How do I bind them to a key combo?

(Sorry for taking so long, I was away)

Thank you.
