New features and changes
This build is extremely alike to build 4032, containing many new changes over build 4029:
 * The Aero Wizards debuted in this build. The CD Writing Wizard is one of these Aero Wizards, which allows users to burn ISO images to an optical disc.
 * This build includes a new red aurora wallpaper. The "longhorn milestone 5" text has also been replaced with "LONGHORN M6".
 * 3D icons are included within the Games Center (which would later be renamed as "Games Explorer").
 * The taskbar clock that was present in builds 4015 to 4029 has been removed and the Sidebar clock has been made more noticeable.
 * The desktop also has a new icon, File a Longhorn bug, which leads to a webpage.

Bugs

 * The Desktop Composition Engine defaults at the CPU processing due to a bug. This makes it impossible to enable the Aero Glass borders.
