Windows 10 Cumulative Update KB4054517 fails to install error 0x80070643

Question

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.

Answer 1

Hi,

The issue you're experiencing with updating your Windows might be due to corrupted components or files.

That being said, have you tried restoring your PC from a recent restore point or performing a System Restore? This will take your PC back to the time you haven't installed the update yet.

If you haven't tried it yet, you may consider it by following the steps under the Restore from a system restore point selection found here.

After doing a system restore, you may try installing the update again.

Let us know how it worked for you.

Regards.
