Microsoft shipped this build to beta testers and its Technology Adoption Program (TAP) partners on Friday, March 24, 2006. This build doesn't include any major new functionality, so I won't be reviewing it separately. However, there are some minor changes, primarily to Media Center, which has been cleaned up quite a bit. Here's a small screenshot gallery that largely shows how little has changed.The next major Windows Vista release is expected May 24, 2006, when Microsoft will ship the Beta 2/RC0 (release candidate 0) version of the operating system to testers and others during the Windows Hardware Engineering Conference (WinHEC) 2006 in Seattle.
