Regular users will be able to download the file April 29th (next Tuesday) when XP SP3 final is expected to be released to Microsoft Downloads i.e. to the manual updates. Microsoft planned to post the patch to its paid services for professionals, MSDN and TechNet, on May 2nd, after the regular users . But after many of them became upset, Microsoft changed its mind and the patches have already appeared on MSDN and TechNet (on Tuesday). In June, Microsoft will push the pack through the automatic updates.

The SP3-updated XP have various subtle improvements, including one that is interesting for physicists – detection of black hole … routers. There are many early users who argue that SP3 brings an approximate 10% performance boost.
