First of all, all versions of Windows are "genuine". There isn't someone out there making a knock-off operating system and selling it as Windows, so let's stop the doublespeak.
What you're trying to stop is unlicensed installations. If I bought a machine from some vendor and he put on a copy of Windows, I honestly don't care as long as it keeps working. If this thing starts popping up, you've made your copyright enforcement problems my problems. Trust me, I have enough problems without dealing with Microsoft's.
Voluntary is another bit of nonsense. It's voluntary but you can't get updates without it. We all know how that goes, we've seen it before.
No personally identifiable information is transmitted. That is until you need to call Microsoft to get your Windows reactivated.
Pirates will work around it. Honest users will be inconvenienced. MS can keep this patch, we don't want it.
