Windows XP build 2410 (main)

First leaked Pre-Beta 2 build of Windows XP. It included a number of new features, such as renaming Professional theme to "Watercolor", new icons that shipped with the final version of XP, IE6 with Media and IM Explorer bars, Outlook Express 6, Movie Maker 1.1, MSN Explorer 1.1, Media Player 8.0, Internet Information Services 5.1.

With this build, we enter the pre-Beta 2 stage. It is unknown why Microsoft skipped the 23xx builds to go straight to 24xx. Notably, it refers to itself as Beta 2 during setup. Unlike the previous builds, it requires a product key.

There is now a new wallpaper. The Watercolor visual style is kept, however, there are two new themes under 'Sample Test Visual Style' that are referred to as 'Chartreuse Mongoose' and 'Blue Lagoon'.

Several applications have been updated, such as Internet Explorer is updated to 6.0 beta 2 (which calls itself 6.0 rather than 5.60 in the about box), Windows Media Player 8 (as included in the RTM) and Windows Messenger 3 and System Restore from Windows ME.
