Finally the last (or they say) update for XP, XP SP3 is here without any bugs. It was stopped last month because of a bug in Microsoft Dynamics Retail Management System.
The download is available on the Microsoft download page or so they say. Many customers have complained that the network is down or showing a 404 page.
Our guess is that many Microsoft users are downloading the 316.4 MB big file and that is creating the problem. If you do not want the update just now just wait a week and you will be fine. Do not risk getting stuck with half a download and you know they will update it in 1 week again.
