Windows XP SP3 and failing Windows Updates

On my work notebook running XP I ran into the issue of WU failing after applying XP SP3.  I found that this solution:

Worked for me.  You’re re-registering the following DLL-files.

Click Start, Run, and enter these commands individually:

regsvr32 /s wuapi.dll
regsvr32 /s wuaueng1.dll
regsvr32 /s wuaueng.dll
regsvr32 /s wucltui.dll
regsvr32 /s wups2.dll
regsvr32 /s wups.dll
regsvr32 /s wuweb.dll
