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.

This build was compiled in evaluation mode and can be installed on the current date.

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. Thus, applications relying on it, such as Outlook Express will crash upon startup.


 * 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.
