Changes

 * The background used during installation has been changed to the aurora found in build 5259. The older setup layout from build 5098 is still retained in this build.
 * This build notably features the Start orb with the colored Windows flag previously seen in build 5212 (vbl_ux_dev_checkin). This build also features the new start menu that was first seen in build 5221 (vbl_ux_dev_checkin_gamesux).
 * A new desktop wallpaper has been introduced, which replaces the wallpaper first seen in build 5054.
 * The Windows Explorer banner background has been changed to a static blue-green gradient.
 * This build marks the first appearance of both Windows AntiSpyware (later renamed to Windows Defender) and Windows Mail, the successor to Outlook Express.
 * A new applet called "Performance Center" as well, which would be known as "Performance Information and Tools" in the final version of Vista.
