Asrock Z77 Extreme Sm Bus Controller Driver

Building a computer for my kid and looking for Drivers for Windows 8.1 64-bit. On ASRock's download page for the motherboard basically had everything I needed (INF - chipset, Broadcom - Network, Realtek - Audio) but nothing for the USB.
So, my question is: will the windows 8 64-bit drivers work on 8.1?
I was able to find Asmedia_USB3 for windows 8 and an earlier Intel_USB3 for windows 7. I just wasn't sure if I should use those to get started or just let windows download them itself once I get everything set up.
Any help would be greatly appreciated.
Thanks

The SM Bus Controller driver brings me through the Nvidia setup WAY faster and then, at the end it just says it's done and closes its window, it doesn't ask/tell me to restart - I don't know if that's what it's supposed to do, or if.
