Windows XP build 2419 (idx02.010113-1154)

Windows XP build 2419 (idx02.010113-1154) is a pre-Beta 2 build of Windows XP, which was released to testers on 23 January 2001.

New features and changes

 * It introduces a Luna-esque setup system, complete with an overhauled OOBE background.
 * The Sample Test Visual Style themes has been updated, including new fading animations and an overhauled Start Menu design.
 * It also has a new boot screen exclusive to this build, resembling the one used in build 2428 but with the old Windows flag.
 * A prototype version of the Flash-based XP tour is included as well (in ), which includes looping images of flowers and astronauts set to Bathers At Asnierès with the title of HelloWorld.
 * The Windows Product Activation application can be found in the Start menu. However, it is set at zero days because it is not added completely, and thus will not trigger anytime. If the user presses next on the application window, it will instantly say that Windows is activated.
 * Spider Solitaire from Windows Me is added, and the Internet Games have gained new icons.
 * Six new wallpapers have been added: Azul, Bliss, Follow me (known as Follow in build 2465 onwards), Moon flower, Red moon desert and Vortec space. The leftover Windows 2000 wallpapers have been removed, with the exception of Windows Me branding wallpaper (which is strangely named "Windows 2000" as opposed to "Windows Me").
 * Nine user account pictures are introduced in this build.
 * Individual beta testers were given unique product keys starting with this build, in an effort to prevent leaks. The product key listed on this page supposedly also worked with other products including timebombed (evaluation) Windows 2000 RTM; it was probably already widely known in 2001, and someone probably tried every widely known product key of the era until they found one that worked. It is currently unknown which of the two ECC public keys in this build's  are identical to previous builds.
 * The copyright date in  has been updated from 1981-2000 to 1981-2001. This remained until build 2600.3180.
 * The copyright date in the Command Prompt has been updated as well from 1985-2000 to 1985-2001.
 * The setup of this build has also been changed. It has the setup, identical to Windows XP RTM except that there are noticable clouds in the background instead of the normal blue gradient which was present in starting with build 2465.
 * The Setup font, which has been changed in build 2211 to Arial, has been reverted to Tahoma. However, Arial will remain when upgrading to this build.

Bugs and quirks

 * Task Manager in this build has visual glitches if Watercolor and Sample Test Visual Style visual styles is used.
 * USB mass storage devices may appear and behave like local disks in Windows Explorer.
 * The 3D Text and 3D FlowerBox screensavers fail to launch due to a  error.

Logon
The Windows subsystem might crash with an access violation when logging off and then logging back on.

Drivers

 * When any wireless network drivers are enabled, the system will bugcheck with the code  caused by the file.

Sample Test Visual Style

 * The Blue Lagoon variant may identify itself as the Chartreuse Mongoose variant.
 * The Sample Test Visual Style is slightly buggy, and has rendering problems with some applications like Solitaire.
