In the coming months, Microsoft will likely release several new Windows Vista releases to testers. What these releases will be called is up for debate. Microsoft will definitely distribute a refreshed build of Vista at next week's Professional Developers Conference. We're just guessing Microsoft will designate this build (rumored to be Vista Build 5219) a Community Technology Preview release. Next up will be Vista Beta 2. Attendees of the Tech Ed 2005 Australia show got a preview of Vista Beta 2, according to various attendees.
