Download details: Standalone Update Package for Windows XP Service Pack 3
Today, Microsoft has released the first candidate of Service Pack 3 for Windows XP. This was quite unexpected since many believed that even a release candidate would not be offered until after Windows Vista SP1 was released. I must emphasize that this is only a release candidate and not a final product. Nevertheless, there is great excitement over this third service pack for Windows XP. The computer gurus over at Devil Mountain Software have tested the preliminary SP3 and, based on their benchmark, they saw a 10% gain in performance compared to Windows XP SP2 (link).
