Windows 7 build 6429

Windows 7 build 6429 has been shown by Microsoft in a remote desktop from Windows XP from videos DTM-AudioFidelityTestingLocal_Training and DTM-AudioFidelityLogs_Training. There has been a debate whether this build is a post-RTM build of Windows Vista or an early build of Windows 7. Due to its earliness, the kernel version is still 6.0.
