Windows Vista build 5209
|Build of Windows Vista|
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 oddly still uses the "Microsoft (R) Windows (R) Codename Longhorn" build tag despite being compiled after build 5112.
