Windows XP build 2481 (main)

Windows XP build 2481 is a pre-RC1 build of Windows XP.

Changes

 * The Windows XP Tour is now fully complete and functional.
 * Introduced the Olive Green and Silver Luna theme colors under the names Homestead and Metallic respectively.
 * The boot and safe to shutdown screens were updated.
 * The sounds used in the final version are added and they're present, but by default, the older sounds used in Windows 2000 are played by default instead, but upon completing the OOBE however, the new startup sound would be played instead.
 * Some of the sounds were compressed or changed to mono, possibly to save disk space.
