Easy enough:

The same drivers for your model.
Select windows 8 (yes – not 8.1 as they didn’t copy them all over!)
You will need under utilities:
ASUS InstantKey Utility (V1.1.3)
ExpressCache (V1.0.100)
ATKACPI driver and hotkey-related utilities (V1.0.0030)
Keyboard Device Filter Utility (V1.0.0.5)
Install those and your keyboard will be back to normal
