On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to the BetaArchive FTP, and was later released in the sixth set of his 33 Longhorn/Vista builds on 29 January 2020, alongside Windows Vista build 5487. This build is only available in the IA-64 architecture.

Bugs and quirks

 * While the Desktop Composition Engine works in this build, the Desktop Composition Engine does not enable Direct3D shaders due to a bug. Because the Aero Glass borders rely on these shaders to function, it is not possible to enable the borders at this time.
 * Search is broken and as a result, it crashes explorer.exe.
 * WinFS is not present.
 * USB Mass Storage is broken.
 * The file saving dialog is broken.
 * The TCP/IP stack malfunctions most of the time.
 * Windows Product Activation is absent.
