Microsoft has released Windows Vista 5472 to the Technical Beta participants, which means this one is still not available to the general public. The build ID is “5472.5.winmain_idx01.060713-1900″ which means it was just compiled on July 13, so this is a pretty recent version.
The ISO image is still about the same size as it has been in the past: 32-bit is 2,629.0MB and the 64-bit is 3,545.53 MB. The original keys that Microsoft gave out for build 5342 (Beta 2) will still work with this build which can be downloaded from Microsoft Connect (NOTE: you must be a Technical Beta participant to have access to Microsoft Connect).
The image above is a picture of the new Vista wallpaper that is available in 5472. You can download the full-size image (1600 x 1200) by clicking here or on the image above. I think it is the best Vista wallpaper yet.
