.NET security updates fail in WinXP SP2. I searched and found others have same problems with WinXP SP3 and no solutions posted in search results. Windows update keeps prompting to install updates, but updates fail every time it's tried. I even tried downloading KB979909, KB982168 and KB982524 which are the updates that fail to desktop and tried to install from there, but failure to install persists. Does anybody know a fix for this problem?
