While Microsoft said the “stealth install” of updated Windows update files — even when users had disabled automatic updating — which we wrote about earlier, was harmless, it turns out it wasn’t quite that simple. For XP users, if you happened to do a “repair” using a repair CD, you would no longer be able to use Windows update … period.
The basic reason for this was that the aforementioned stealth update replaced certain Windows update files. When a repair is done, that file is replaced, and Windows Update is no longer able to function. Nate Clinton, program manager for Windows Update, said on the Windows Update blog:
Here’s what we found: when an XP repair CD is used, it replaces all system files (including Windows Update) on your machine with older versions of those files and restores the registry. However, the latest version of Windows Update includes wups2.dll that was not originally present in Windows XP. Therefore, after the repair install of the OS, wups2.dll remains on the system but its registry entries are missing. This mismatch causes updates to fail installation.
I was confused at first, but what he means is the registry entries for the new wups2.dll are missing — I think. BTW, this is the same Nate Clinton who initially said the stealth update was harmless.
I’m being a little harsh here; it’s really the combination of the update and the repair that cause the issue.
How do you fix it? There’s a Microsoft KB article on it, KB943144. Unfortunately, while people like you and I won’t have issues with the procedure, it’s certainly nothing most users would be comfortable with. More
