The successful update was from a manual download and install of the January cumulative. I will try running Windows Update soon. But this is awesome progress, I have been stuck with this issue for a couple of months. Thank you VERY MUCH!
You're welcome! Glad to hear you were able to manually install an update without a rollback issue - and error 0x800f0922 for the latest Cumulative Update.
Please let me now if there are any remaining issues or we can mark this thread as solved?
