Yeah, I'm not talking about Windows Updates though. We have free tools like WSUS, or SCCM (not free) available that give you fairly good control over the patch management processes. Security updates and patches are generally a good thing, we want those, they have benefit and value. Compared to WGA, which has absolutely NO "Genuine Advantage" to a company that creates system images with installation media from legitimate sources, and doesn't utilize PC's from sketchy OEM's with pre-loaded software. We know our software is "Genuine" and not tampered with because we paid dearly for it, had it shipped to us, or downloaded it directly from Microsoft's sources ourselves and checked the hashes. Anti-piracy measures like KMS only create additional administrative overhead in a business context, especially in a small to medium size business where we get little to no volume purchase discount anyways. Yeah KMS is free, but it's one more logically unnecessary system that we have to manage just to appease MS.
What RMingin was saying, is that this fix will affect the anti-piracy methods, which will affect everyone, but only temporarily annoy the pirates.
TL;DR: Dear MS, it shouldn't be easier to pirate your F'n software, than to purchase and use it legitimately, quit pissing off your paying customers.
