Is it possible now to run 8 x AMD RX570s on Windows 10 on the AsRock H110 Pro BTC motherboard?

I have 6 RX 570s running fine on the motherboard and now have the cash to buy 2 more.

I have a version of windows  that is about 6 months old (Windows updates turned off).

Can I just plug in the 2 extra AMD cards and they be recognised?  The Asrock specs sheet says 8 AMD supported but it doesnt specifically say under Win10 rather a miner called GUIMiner which I know nothing about.  I want to use Claymore on Win10.
