3 Updates get error code 800B0100

[canu49]

I have 3 important updates that have been failing with code 800B0100 for a couple of months. I've trie sys. rediness tool, mr. fixit and even tried clean boots with and without anti virus and wirewall. I'm really stumped. The updates are: KB2584146, KB2644615 and KB2631813.
I've included the Checksur file from the rediness scan.
