Our intention behind the original terms was genuinely geared toward combating piracy; however, it’s become clear to us that those original terms were perceived as adversely affecting an important group of customers: PC and hardware enthusiasts. You who comprise the enthusiast market are vital to us for several reasons, not least of all because of the support you’ve provided us throughout the development of Windows Vista. We respect the time and expense you go to in customizing, building and rebuilding your hardware and we heard you that the previous terms were seen as an impediment to that -- it’s for that reason we’ve made this change. I hope that this change provides the flexibility you need, and gives you more reason to be excited about the upcoming retail release of our new operating system.
