Microsoft Corp. released the beta of Windows Vista Service Pack 1 to a private group of testers, taking one step closer to the anticipated official launch in the first quarter of next year. In late August, Microsoft for the first time offered a release schedule for the long-awaited SP1. At the time, the software giant said the beta would become available this month to between 10,000 and 15,000 testers.
