Keyboard not working properly on boot camp?

Hello! I recently got a new wireless keyboard for my mac after 3 years of use.

The thing is, when It's in OS it works perfectly, nothing is wrong and the keys do what they're supposed to be doing. HOWEVER, when i switch to my Windows partition, the F keys wont do what they're supposed to do, no brightness adjustment, no volume adjustment, I tried working it out with the Fn key in the bootcamp settings but it didn't seem to work at all.

Also some of my keys have swapped places, specifically the ª and > keys, I tried with different language settings but nothing seems to work.

I already tried to reinstall the bootcamp drivers but nothing.

Anyone know how to fix this?
