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.

    I think I've got this:

    1- Disable automatic update 

    2- Clear temporary files running "Disk Cleanup" (you should clean up all system files too)

    3 - Download and run this utility from Microsoft: https://support.microsoft.com/en-us/help/10164/fix-windows-update-errors

    4 - Run the Windows update repair tool (the built-in utility you'll find in "Settings" https://www.microsoftpressstore.com/articles/article.aspx?p=2467489)

    5 - Download and run the KB4054517 offline installer (https://www.windowslatest.com/2017/12/13/direct-download-links-kb4054517-windows-10-build-16299-125/)

    6- Reboot and re-enable the automatic Windows updates. Check and you'll find the KB4054517 is now properly installed

    I don't know if all the cleaning and repair tools are strictly necessary, but I did the above and it worked.

    try this:

    Here is an easy fix to a failed KB4054517 update

    • Go to Settings > Update & Security > Windows Update > click Viewed installed update history
    • Click Uninstall updates
    • Click Security Update for Microsoft Windows (KB4054517)
    • Click Uninstall (this might take a while)
    • Reboot (it'll say it's updating)
    • After it reboots go to Go to Settings > Update & Security > Windows Update > Check for updates

    - KB4054517 is shown as an update

    • Update > it reboots and installs the update
    • After rebooting go to Settings > Update & Security > Windows Update > click Viewed installed update history

    - KB4054517 successfully installed

    • OS Build 16299.125

    These steps don't work for my problem and error code.

    I had two new KB's show up and install today:

    KB4048955 and KB4058043.

    KB4054517 still won't properly install. It thinks it has been installed twice but my build is still  16299.64 instead of 16299 .125

    AND I have a new error code on the KB4054517 installation that failed

     0x80240034

    Hi, 

    Thanks for this info.

    I had two problems with KB4054517.  I have an old Dell desktop computer and a newer Dell plus a laptop. The cumulative update worked on the newer Dell desktop and the laptop but hosed the older Dell.

    First it gave me a blue screen "Inaccessible boot device".  Tried to go into safe mode, did not work. Tried troubleshooting repair, did not work. Tried system restore. All my restore points failed trying to restore. I had to reset my PC which installed the OS but lost my apps. 

    After that was able to boot up and get into windows 10 but noticed that it took a very long time to boot up and to shut down or restart. Kept getting that not to shut down since windows is updating or something like that. Tried to repair the windows update. It suggested and flagged a restart. But KB4054517 was stuck at install at 99%. It would fail and said it would Retry. But it was an endless loop of restart shutdown and boot up which each took a long time with windows saying not to turn the computer off.

    I then followed some suggestion in this thread.

    I had to disable windows update service, which was in Manual (trigger start) mode, and then do a restart. I checked windows update itself and it said up to date. I looked at the windows update service and then enabled it and set it on Manual.  Then I went to microsofts site and downloaded appropriate KB4054517. https://www.catalog.update.microsoft.com/Search.aspx?q=KB4054517

    I then manually installed it. It worked.  Prompted a restart.  I went back to windows update and the cumulative update was installed, windows update said it was installed and I was up to date on updates.

    Went back into windows update services and made sure it was enabled and I left it on Manual (trigger start).   

    Knock on wood this seemed to have stabilized things.  Now to reinstall my apps. 

    Not quite sure what the reason was for all the problems but microsoft hopefully is investigating and does something as this costed me two days and all the programs that I had purchased for the old Dell computer. 

    I hope that this helps others if in similar situation.

    Oh by the way I did a sfc /scannow. Did not find any issues. And also a chkdsk c: /f /r.

    Microsoft needs to address this issue. Some people are not as computer knowlegeble than others and cannot solve such issues

    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.
