Windows 10 home, new computer with CPU Intel 8700K working well, version 1709 installed.   

I noticed that windows update gives error 0x80070bc2 when trying to install 2017-11 Cumulative update for Windows Version 1709 for amd64-based systems KB4048955 (and before KB4043961) ... getting a sort of a loop as it requires a restart to finish installing but at any restart gives the same message and does not install.  

Tried various things such as sfc scan, dism, troubleshooting windows update, manual install etc.  Nothing works.  Other updates such as KB4048951 and KB4051613 installed correctly in the last few days.  Can someone help?

Windows for home | Windows 10 | Windows update

This seems to have worked for me:

  • Right-click on Windows key and select Command Prompt (Admin).
  • Type the following commands in Command Prompt window. To execute them, press Enter after each one. 

SC config wuauserv start= auto

SC config bits start= auto

SC config cryptsvc start= auto

SC config trustedinstaller start= auto

  • Finally, restart your PC and try to install the update that was previously returning the 0x80070bc2 error.

    A variant of this approach seems to have improved but not completely corrected my situation.  When I looked at @Devib/bosson's post, I was able to use the "services" UI to check these services.  On my system, the wuausrv had been set to "Manual", possibly by a script run by a remote support session I had with Microsoft which "fixed things" only long enough for another update to come out.  My system now tells me it is "up to date" and does not try to reboot itself.  However, the "update history" includes multiple entries for the same updates some with "awaiting reboot" notations eve though other instances are listed as "installed."

    I also tried using the "image checker" tools listed under solutions for "performance issues" and ran an hour long internet script that produced an unintelligible log file, and "Fixed" a problem I have had with the appearance of the "Network Name" assigned to my internet connection in the "Settings" display since the days of Windows 7 (x64) on this system made in 2010.  I have had the same router configuration all these years, although the hardware has been changed.  When I first set this system up, it was connected to Ethernet but would not update Windows 7 (X64) until I set up the wireless radio to talk to the wireless connection to the same router that provided Ethernet.  It downloaded and was rebooted three days straight back then before it stopped applying updates and started working as a useful computer!  The name of that wireless connection always appeared on the "Network" settings screen of Windows 10 until yesterday when I ran the image checker!  

    I still see three instances of the update that prompted this thread in my "Update History" one showing installed, another a day later showing the same update as installed and one with the coded error message 0x80070bc2 appearing.  I believe my "problems" actually started with these files as released earlier in November of 2017 and then updated by Microsoft.

     I got these installed using the downloadable installer, but the log screen under Windows Update on my system still shows the installation as "pending restart" even though the script that checks for updates says I do not need any and am "Up to Date" as of February 9th.

    "....this fixed my problem and allowed my updates to go through. Perhaps Microsoft should 'e' mail all users of Windows 10 about this successful guide to fixing the problem."

    Yes, I agree. Microsoft should Post it's Fixes to the Upgrade problems. Put your reputation online, Microsoft. Stop hiding behind surrogates.
