ran troubleshooter, it fixed 2 problems and the third problem said some files are missing and it could not fix it.

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.

2017-12-14T03:24:15+00:00 Windows event viewer is showing that KB4054517 was successfully installed on 13/13/2017 1:36:52. Windows update log shows it failed to install. OS build is now 16299.125.
I assume OS was updated and problem is with update log. The only relevant fact I can see is the update ran unattended overnight and i the morning I had a error message about a job that failed to start. Unfortunately I did not make not on the error message and simple closed windows and restarted. Update showed that KB4054517 install was pending a restart, which I then did and received the error message that it failed to install. That was approx. at 1pm local time.

2017-12-13T16:38:06+00:00 I just had this same problem happen to me today right now after my computer restarted after downloading&installing this latest cumulative update.
I don't want to use restore feature or try to install it manually, because it probably fails like it has with others who has posted to this topic earlier.
I don't have any useful info neither the answer for how to fix this problem other than suggesting MS support to re-read the posts done by Mountain BnJ and others and giving us a way to fix it somehow.
Thanks in advance.
