Have you looked at your update history and right clicked on the failed update to see if any info is available about the problem.
The Update is "An automatic updater of revoked certificates", and mentions possible problems with systems were the URLs are preset into the system, normally enterprise type systems, if that has any relevance to your situation.
I don't suppose opening a command prompt and doing a ipconfig /flushdns would help. Since they are changing the URL, it might be related.
I have checked the update history and possible problems. Microsoft gives absolutely no specifics on how to troubleshoot. I have also performed the obvious Restore System to previous dates but that doesn't help either. Thanks for your post.
The details of the failure do not give you an error number?
You may need to copy the WindowsUpdate.log from C:\Windows to your desktop. Then copy the last few days of the log and paste into a notepad file. Zip it and attach, or just attach using the paperclip on the Advanced Reply dialog.
If none of that works, the big hammer seems to be renaming or deleting the SoftwareDistribution folder in the C:\Windows directory. If you do this, and I have, it will take some time for your system to catch up.
Your other updates appear to be working fine, so that would seem to confirm there is some problem with just this one.
