Windows 10 Cumulative Update KB4054517 fails to install error 0x80070643

We just got our "second Tuesday" updates (12/12/2017) on our W10 machine running V1709.

The cumulative update KB4054517 failed with an error code of 0x80070643.

The only thing we've discovered so far is that this machine will not display our other 3 PC's on the network when we select "Network" in File Explorer.  But all three other PC's can "see" and access this PC no problem.  And we ran a batch backup job on the affected PC and it was able to copy files from all three other PC's.  So it's just a display problem in File Explorer -> Network.  

We've run Windows Update Troubleshooter and told it to Apply Fixes whenever it prompted us, and it DID report that it found and fixed three issues:

Potential Windows Update Database Error - Fixed

Windows Update Component Must Be Repaired - Fixed

Check for pending updates - Fixed

After exiting the Troubleshooter, we clicked on "Check for Updates" again and it said "Your device is up to date". 

We noticed that the build number after the "failed" update had changed to 16299.125.  So the system thinks it DID install something newer than it had before, but Windows Update thinks the cumulative patch failed to install.

BTW, the other "Second Tuesday" patches (Adobe Flash KB4053577 and Windows Malicious Software Removal Tool KB890830) both installed OK.

    All this is FINE if you had not placed faith in that Microsoft Updates, have no effects on currently installed software. Updates that fail, should allow YOU to roll them back, and mark them to never run. You could do that in Windows 7. So why did that function get removed from Windows 10?

    Additionally, by now, the log should reflect that, and remove failed entries.

    Beyond that Microsoft should be expected to investigate and release a FIX as they commonly do, for the end user. NOT registry hacking, as that is beyond the norm, and nor should the end user expect to have to perform such steps as being so routine.

    Microsoft seems way too focused on integrating NEW applications to wow the user. Not everyone cares about new things, but fixing old things should be the top priority.

    That's why Windows Update was created in the first place, to fix the remaining bugs and holes in the overall system, that keeps things running smooth.

    Yes, and it shows as Windows 7 Backup. I am not opposing that, I just would have figured that by now, they would have refined it, and made it part of the Metro Style Settings, rather than in the control panel.

    Further that it is horribly slow, and I once tried to restore with it, from the recovery media, and it failed. No errors were given to the backup either. 

    Compared to other free products, it is a horrible piece of software. I would not place ANY faith in it.

    That's just me.
