Issues installing updates after repairing XP


We received reports today that some Windows XP customers haven’t been able to install updates from Windows Update/Microsoft Update with the latest version of the Windows Update client.  We are only seeing this issue when users have performed a “repair” on their Windows XP installation. I wanted to take a minute and let folks know what we know about this right now and what we’re doing about it. 


After getting the reports, we began actively reproducing and investigating the issue. We have identified the root cause and the steps to resolve this issue. 


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.


If you experience this issue, you can contact customer service using the contact info at http://support.microsoft.com/security.  Additionally, a KB article describing the steps to resolve this issue will be available soon. I will update this blog with a link to the KB article when it is available. In the meantime, here are the steps included in the KB:

    OK, forgett what I wrote above. There ist a wups2.dll file in the %windir%syswow64 folder on XP x64. I looked accidentally in the syswow64 folder of Vista x64. Sorry for that.

    Actually, you already have a MSKB article published dealing with the "issue": http://support.microsoft.com/kb/916259/en-us

    Add the "download WUA 3.0 and install it with parameter /wuforce" line there, consider a change in the subject of the MSKB article and everything is well.

    There’s IMHO no need to respond to every FUD published by some "journalists" and "news sites".

    Bye,

    I’m using Windows XP x64 SP2 at the moment and I did not performe a repeair installation yet, so I don’t know if I’m right or not.

    At the moment there is no wups2.dll in my %windir%syswow64 folder but the windows update works well. I only have a wups.dll. The wups2.dll only exist in the %windir%system32 folder.

    So the question is, which name is right for the file in the syswow64 folder? wups.dll or wups2.dll. Or appears the wups2.dll after a repair?

    No software is perfect but I have been very impressed with XP and auto updates. I appreciate the ability to keep my system updated with little effort on my part and take advantage of most automatic update style features for XP, and also for other OSes and applications. In my opinion the small risk of getting a bad update is vastly outweighed by the risk of being behind the curve, since most updates improve stability or security.

    I had to use the same fix again today. It looks like this is going to be a standard thing when ever we use repair install. Makes the process even longer. At least it works.
