It took me some time to figure this one out. After installing SP3 on my Windows XP virtual machine I was no longer able to update my Windows with Microsoft update. After some debugging I found out that Windows installer was the problem. All windows updates failed directly after installation.

The message I received was: the update or the updates were not installed successfully.

What I did to fix the problem was remove SP3 for Windows XP installed Windows installer 3.1, applied all available updates and last I reinstalled SP3 for Windows XP.

After I fixed it on my Virtual Machine I found this article on the support page of Microsoft but by that time I knew what to look for so… maybe I can save somebody else his or her time by giving you this article up front.

This article has a more simple solution to the problem. This article Explains how to register a DLL that is not registered correctly on a Windows XP SP0 machine where you install SP3. The steps

net stop wuauserv

For x86
regsvr32 %windir%\system32\wups2.dll

for x64

net start wuauserv
