Could you please let Jake Doe now that his post under:

How to fix Windows update error 0x800f0845 on Windows 10?

appears to be out of date, since Windows no longer shows “Startup Settings” in its “Advanced Options” Menu. I am also getting this Update failure of which he writes with the latest Windows Update KB4103721
(see so it is appearing in more than one update (the article states it only appears solely for update KB4056892. I had to use (from the command prompt)
in order to get the machine to boot in safe mode, and then it automatically uninstalls the faulty update. Perhaps a re-write of this article is needed. Just thought I would let you know.
