After running a Repair of XP you go to the Windows Updates Site to get the 80+ Updates which you need to reinstall. The Updates download but will not install.

This is due to a silent update that Microsoft deployed widely in July and August.
Since this download of new support files for Windows Update, users of XP's repair function have been unable to install the latest 80 patches from Microsoft.

The fix is to register some dll files

Start/Run and type in the box
regsvr32 /s wuapi.dll
OK

Repeat the above for all of the following dlls
regsvr32 /s wuaueng1.dll
regsvr32 /s wuaueng.dll
regsvr32 /s wucltui.dll
regsvr32 /s wups2.dll
regsvr32 /s wups.dll
regsvr32 /s wuweb.dll

The Updates should install now
