Windows XP build 2517

Windows XP build 2517 is a pre-RC 2 build of Windows XP.

Changes

 * Like build 2531, Setup now uses Arial instead of Tahoma.
 * During startup of text-mode setup, the title now reads "Windows Setup".
 * "Version 2002" is no longer shown on the screen before the out-of-box experience.
 * After the first restart during the upgrade setup, it shows Windows bootscreen with the gray loading bar, just like Windows Server 2003 build 2493 did.
