Windows Vista Build 6000?

I have the Windows Vista build 6000 installed on my computer, and I installed it with a beta CD key, installation went through with no problems, and when it auto activated it went through fine. When I view my system information, it says I have a genuine Windows product, and I am activated. I know that RC1, RC2, and other various beta releases have a built in timebomb and none of them will work after June 1st of next year. But since 6000 is the release to manufacture build, does it also have this timebomb? I'm fairly sure they never distributed it themselves like the other builds, which would make mine a pirated copy I guess, but since it's the final build would it have it in there? Is the timebomb related to them keeping track of your cd key or actual built in software in the previous versions? If it is going to stop working then, do you know of a crack that will get rid of it?
