Windows XP build 2481 (main)

This build is the official pre-RC1. The Windows XP Tour has been fully set up and the alternative Luna colours are available (they are called Homestead and Metallic which became Olive Green and Silver respectively). The bootscreen was replaced and there were new XP sounds added, despite only the shutdown and startup ones are enabled by default, the others need to be manually enabled, otherwise the Windows 2000 ones will be enabled.
