I also am having this exact same problem with the same updates, plus another one. Updates KB2973337, KB2982378, KB2973351, and KB2984972 all fail to install with error code 800B0100. I have "googled" this error and found quite a few with the same error 800B0100. Some were for the same KB's and others were different. I have tried two different MS Fixit's, the system update readiness tool, and they still failed to update after each try and reboot. I manually downloaded the above updates from Microsoft download center, and they failed to install. I found several links about doing a net stop wuauserv and renaming the c:\windows\softwaredistribution folder and then restarting wuauserv and rebooting and then retrying and that also failed.
If I should start my own thread and work with someone else, that is fine, just let me know or if this is OK to jump in here, I will follow this thread. I am at my wits end. I would hat to have to reload windows because of MS update failures. Thanks in advance for any help!
