Updating video drivers in boot camp
Once your Windows 10 installation is up and running, Boot Camp 6 will allow you tap into a number of your Mac's normal features USB 3 and USB-C connections, Thunderbolt, your Mac's built-in card slot (if applicable), and your normal Mac keyboard, trackpad, or mouse.
So I updated my Bootcamp installation to Windows 10 yesterday, and it looks like MS uninstalled the AMD driver (which is fine).
If you're a huge Apple fan, but you're tempted to give Windows 10 a spin and see how it feels, now you can.
Rather, now you can without having to buy a separate desktop or laptop computer, since Apple now officially supports Windows 10 within Boot Camp.
Try this: Apple DL1443: Boot Camp Software Update 3.3 for Windows.
It's called an update, but I suspect it doesn't require any pre-existing installed drivers.
I'm setting up my Mac Book Air for a Windows-only boot setup. It already had r EFIt on it, I just connected a Windows 7 boot thumb drive, and away I went.
However, it seems Apple does not let you download Bootcamp drivers outside of their assistant tool.
Before you upgrade, you'll first want to make sure that the Mac you're using actually supports Windows 10 x64 to begin with.
I went to the AMD site and downloaded driver 15.7.1.
After the download finished and the installation began, the installer told me something to the effect of "no valid driver could be found for your system".
(Apple provides a helpful list for that.) Assuming it does, you'll want to boot into OS X and make sure that you have any and all software updates installed.
Switch over to your Boot Camp installation of Windows, and open the Apple Software Update tool.
