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.

    That's basically what I did.

    Tried everything in these posts over a period of 3 days.

    I put off using the Windows Media to reinstall because I originally had a Windows 8 recovery disks and didn't want to re-install that.

    Finally I just gave up and used the downloaded Windows 10 Media on a USB memory stick and manually re-installed it, I found at the same website your link pointed to.

    It installed Windows 10 Home, I had Pro.  Worked great, of course what I did wipes all your documents, setting, programs etc.  But since I have two other computers which were successful with the KB4054517 update I still had all the documents, web favorites and etc.  

    It was an older computer and thought I would make it a clean start, get rid of all the accumulated garbage.

    My computer is now working great.

    And it finally updated my computer to Windows 10 Pro.

    I have the same issue and have tried everything. I think this update  2018-01 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4056892) is no good and after system restore and the clean start this is what I see on my update page.

    Some settings are managed by organization. This is my Personal computer running Win 10 Pro
