Windows XP build 2223 (main)

This build identifies itself as 'Whistler 2001' in the start menu and login screensaver. It also has the Neptune login screen that would remain with Whistler until build 2428 (beta 2). It also is the first leaked build to include the OOBE.

Contrary to popular belief, 2223 is actually the first build to have new theming, however unlike 2250 it does not have an accessible UI like Watercolor. The theming of 2223 is in the file, Business.thx.
