Roger,
Quick question, With the help of Windows Genuine Advantage: Microsoft is able to block down pirated software to get updates from Microsoft Automatic Updates. Ofcourse, these machines will not be patched with all the latest vulnerabilities out there. As you mention in your blog
"We are delivering critical security updates even to people who have stolen our software in order to protect the ecosystem from their machines!"
I think if you are not using Genuine Windows, Microsoft doesnt provide critical updates. Correct me if i am wrong.
