Microsoft has started talikng about Windows Vista Service Pack 1 (SP1) features, release, previews and testers. Just as news was leaking that Windows XP SP3 was released to few testers, they confirm that a small group of testers has got a preview of the Vista SP1 Beta.
Microsoft announced that after these small group of testers check it out, the next pre-release will be available to testers via MSDN and TechNet subscribers.
