First, it went to a select group of technical beta testers. Then to those who had tested Beta 2. As of September 14, however, Windows Vista Release Candidate (RC) 1 is now available to anyone interested in testing the product. The bits can be downloaded from the Vista Get Ready site. Microsoft's goal is to allow up to 5 million individuals, total, to play with this near-final test build. After RC1, there are no more public Vista builds coming – just an undetermined number of private ones before the product goes to manufacturing.
