I'm getting the same thing. Error 80073701. Customer support was unable to help with this so far and command prompt won't allow me to change the folder names per MS support website online self help instructions. Kept saying "access denied".

I tried the "Windows Update" trouble shooter to no avail.

"Control Panel" -> "All Control Panel Items" -> "Troubleshooting" -> "Fix problems with Windows Update"

Thanks for the suggestion. That worked. I had recently run the disk cleaner and was assuming it would not need it again for this. Apparently there are problematic updates often and the cleaner really helps to get rid of them.
