Windows Vista build 5209

Windows Vista build 5209 is a pre-Beta 2 build of Windows Vista. It was presented by Steve Ball in the Channel9 video, Learning about Audio in Windows Vista, which demonstrated the new audio features in the operating system. This build still uses the "Microsoft (R) Windows (R) Codename Longhorn" name on the desktop watermark despite being compiled after builds 5112 and 5212.
