Windows Longhorn build 4032

Windows Longhorn build 4032 is a Milestone 6 build of Windows Longhorn. A screenshot of the build was leaked on the BetaArchive Discord server on 27 November 2018. On 3 December 2018, this build was leaked to the BetaArchive FTP by ReflectiaX, along with 4020. This build is extremely similar to build 4029 (Lab06).

Setup
Setup overall is similar to previous builds of Longhorn.

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.

Sidebar
The Windows Media Player tile is unstable and will error out on both playing music and while adding the tile.

Installation
The installation media is not bootable due to missing bootcode. You can add a loader yourself. For this:

1. Open the install.wim file using any application that can modify ISOs.

2. Open the "0" folder.

3. Copy all files from there to the ISO distribution.

4. Save the new ISO.

Alongside, attempting to upgrade from an older build of Windows Longhorn results in a file copy error (except build 4031). This error does not occur when doing a clean install on top of an older build.
