From Neowin: Thats right folks, just like Windows XP SP2 and Longhorn a few weeks back another build of Windows XP SP2 has found its way onto the internet. Holding the build number 5.1.2600.1185 (xpsp2.030313-1931) there are clear indications that SP2 is progressing in it's development and might well be ready to go into its beta stages sooner than we expected.
