Windows Longhorn build 4033 (idx01)

Windows Longhorn build 4033 (idx01) is a Milestone 6 build of Windows Longhorn. 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.

Desktop Composition Engine
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.

Explorer

 * Search and cut/copy-pasting are broken as it crashes explorer.exe.
 * WinFS is not present.


 * USB Mass Storage is broken.
 * The file saving dialog is broken if explorer.exe is running.

TCP/IP bug
The TCP/IP stack malfunctions most of the time.

Windows Product Activation
Windows Product Activation is missing.

Timebomb
It is one of the notable Longhorn builds that has a broken timebomb and can be installed on the current date.
