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?

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.

    This actually solved my issue. I had tried everything else and when I came upon this post I was skeptical it would work. Thankfully I was wrong and this solved my problem on both of my PCs that stopped updating after the new year!!

    Thank you so much!

    Dan Ayres,

    I have used my external backup HD to restore files. It works fine. But a backup will not re-install an application. I have found PKEY files but they may be from Office 2003. In any case I can't reinstall without the Office 2016 app. I lost a lot of my stuff and I haven't ever gotten a paycheck from Microsoft. I received a free copy of Windows 10 when I agreed to let MS monitor my use. I didn't agree to be a beta tester.
