MacBook Pro 2017 Apple wireless magic KB and magic mouse not working in Bootcamp partition

Got a strange one. My wireless magic mouse and keyboard was working fine last night in Bootcamp, switched my MBP on today and booted into windows and they stopped working.

They work fine when booting in Mac iOS and on the virtual Win 10 machine, just not when booting directly into Bootcamp.

I did change the startup boot priority in MB preference under start up disk, don't know if that would have something to do with it? All driver are correct and present.

Any ideas?
