I had same problem and this helped
-Stop the "Windows update" service.
-Create a new directory "C:\Windows\SoftwareDistribution.old"
-Move contents of "C:\Windows\SoftwareDistribution" into that new folder
(cut & paste)
-Start "Windows update" service.
Now update should work again. At least for me it did.
You can delete the .old folder
