Hey, i just built a system using this mobo.
They've put up the drivers, bios updates and utilities. Here is the link https://www.msi.com/Motherboard/support/B250I-GAMING-PRO-AC.html#down-bios
Windows 10 didn't detect my mobo wifi drivers, so i had to manually install it using a usb. So i installed the wifi drivers and the live update utility, and let the utility download and install all the drivers.
