Windows 10 Cumulative Update KB4054517 fails to install error 0x80070643

Anonymous

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.

Proceed to the Microsoft Update Catalog (as we all do when updates occasionally fail to automatically install) and install the update MANUALLY.

Ok, I found this , and combined with manual down load - worked !!!

Its probably a glitch and you need to reset the software distribution folder.

I would suggest you to rename the software distribution folder by following the steps below and check if it helps:
1. Type cmd in the search bar.
2. Right click and select "run as administrator"
3. Copy the following command and press enter after each line:
net stop wuauserv

cd %systemroot%

ren SoftwareDistribution SoftwareDistribution.old

net start wuauserv

Restart when complete.

Best,

I turned off the windows update service and tried the manual install 3 or 4 times over the several days of this mess.

Tonight, after making a couple of types of recovery images of the C drive, I tried installing KB4051963 to bring ...64 up to ....98 as some people have done. That update also failed to install manually.

THEN I check for windows updates and it says computer is up-to-date. I rebooted again after a while and it did a check and still says computer is up-to-date without installing KB4054517. I checked in installed items, and it's not there.

I wonder if MS has recalled the update.

My version is still 16299.64
