There is another option.
I am currently running 7 Pro on an X170 board and of course it is much older too....but you can still try this if you want to, But even fernando's "pure" drivers are not covering the newest boards
Open the Spoiler links for the Intel drivers on the win-raid link and look for the closest driver package for your board.
Put the drivers on a usb drive.
Now it been a long time since I installed W7 on my (or any other) pc but I did not need to make an Windows 7 .iso with the drivers because this was only a one time thing so (my memory is a little dull on this part) as your installing Windows 7 Pro, you'll get an option to add drivers, Select that option and point to the usb drive that has the fernando drivers on the usb drive, they should install providing they are compatible with your board. Let W7 finish it's install and you should be able to use your usb 3.x devices. (hopefully)
