Windows XP build 2415 (Lab06 N)

Windows XP build 2415 (Lab06_N) is an unleaked pre-Beta 2 build of Windows XP, which was shown at CES 2001 on 6 January 2001 to demonstrate the new Luna user interface. It includes a noticeably earlier version of the theme with differences compared to builds 2423, 2426, and 2428, such as the use of a larger font for window captions and a different design for the Start menu with a gradient background for the righthand pane, a blue Log Off button, and, most obviously, the older Windows flag. The Bliss wallpaper was used for the demonstration although the default wallpaper used in later builds was Red moon desert until after Beta 2. The build also features the older Windows logo on the Start button, which suggests that the new graphic has only been introduced in January 2001.
