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.

    The way I solved the issue re KB4054517  Error 0800705b4

    After downloading the proper KB4051963 and KB4054517 from the Download Catalog

    1 - Un-intstall the KB4051963, and reboot. (10.0.16299.15)

    2 - Re-install the KB4054517, which will partially install, then fail (10.0.16299.15)

    3 - Re-install the KB4051963, which completed on the computer I was working on.(10.0.16299.98)

    4 - Re-install the KB4054517, which now completed on the computer I was working on. (10.0.16299.125)

    Finally got it installed. This is what did it...

    According to this  https://www.computerworld.com/article/3199077/microsoft-windows/windows-10-a-guide-to-the-updates.html

    The update progression from OS Build 16299.68 is via 16299.98 to 16299.125

    So I manually updated using KB4051963 to OS Build 16299.98 and then manually installed KB4054517.

    The router was turned off to stop the automatic updater which was trying to butt in.

    Took a while but there were no further problems.

    Don't know why KB4051963 was missing.

    I would expect Cumulative updates to be designed to contain all previous update files. If that is the case then KB4054517 must be incomplete and is more like a "Delta" update.

    This worked for me as well. Thanks! Damn thing wasted hours of my tim
