I have just had a few questions about my previous post about XP SP3 so here are some more details:
Windows XP Service Pack 3 (SP3) Release Candidate (RC)
Windows XP SP3 RC is a rollup that includes all previously released updates for Windows XP, including security updates, out-of-band releases, and hotfixes. It contains a small number of new updates, but should not significantly change the Windows XP experience. Technet subscribers: download it now. Broadened availability of this service pack will be based on feedback from Technet Plus subscribers.
