You're not at all annoying, I'm on this forum to get help and learn and your posts are the most helpful.
First failure was 12/9, Definition Update for Windows Defender KB2267602 (weird that a definition update would fail). Then Security Update for Internet explorer KB3022827.
By rolling back if you mean using System Restore I just opened that and bummer, no Restore Points (I used to manually create them but then got used to Windows doing it automatically before certain updates). I can uninstall updates. These are the ones I can uninstall. I recently re-formatted this partition and re-installed the first build and then let it update and install build 9879 because Win10 wouldn't load.

To tell you the truth, I don't know if I want to uninstall all 7 updates. Since it is, at least, working I'm just thinking I'll reinstall Office and wait for a new build in January.
