Windows Longhorn build 3663
|Build of Windows Longhorn
Windows Longhorn build 3663 is an unconfirmed and controversial build of Windows Longhorn. It is the earliest known build for which screenshots exist; one initial set of screneshots was uploaded by one "Calvin Zhang", on 23 August 2002.
Visual changes in the build include the replacement of the colored Windows flag on the start button with a single white color variant, along with the default wallpaper including Longhorn branding. It also seems to have the login screen from build 3683 and disk space indicators in Explorer. Otherwise, this build is not much different from Windows XP or Windows Server 2003. It is unknown if this build has the Plex theme due to the theme in the screenshots being set to the Silver variant of Luna.
