That's easy. Install Win7 64-Bit and give up the chase for something that isn't worth chasing in the first place.
I'm not being cynical...just questioning what the ultimate goal is. Stability...productivity...predictability...makes my day. Spending a huge amount of my time chasing the solution to a problem that isn't even a problem unless you absolutely must have Win 8 is just a bad use of a very finite resource called time.
