Windows XP build 2474 (main)

Windows XP build 2474 is a pre-RC1 build of Windows XP. This build replaced many (but not all) Whistler references with XP, also, a different Windows flag, which is animated, was added at the login screen, which would later be changed again in build 2481. It now calls itself Windows XP RC1 in setup and it has a new boot screen with the Windows XP flag.

This is one of the first builds to use the modern Windows XP Logo Testing implementation, this can easily be seen when upgrading to this build as almost all hardware will result in the warning that such hardware may not work and cause instability.

Now you can see Windows XP background, sounds, and eventually, the start button. At the bottom-right corner there are Windows XP Professional instead of Windows Whistler Professional.
