Q: i need to update my graphical drivers in bootcamp using windows 10. how do i do this

The Boot Camp drivers are a good starting point and will install everything you need to get started (such as for the Apple specific hardware features).

But the boot camp drivers are not updated very often, and you should definitely update the AMD drivers for display adapter which are probably far newer than what Apple has included in its Boot Camp support software,however to get to the option on window on the search menu type in apple if you used bootcamp to install the O.S i will pop up there and give you the latest drivers.
