WGA is an important capability built into Windows Vista. Today, we announced changes to this capability that will be brought to your system in Vista SP1 and in Windows Server 2008. For the full announcement, check out the WGA Blog entry as well as the interview with Mike Sievert. Personally, I like the idea of reduced functionality for bootleg systems, but there are much smarter people in Redmond studying this topic and reacting to customer feedback.
