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 is what I did after 6 weeks, a clean install and loss of address books, archives and bookmarks:

    1. I went to "Settings" and chose "Windows Update"
    2. then I chose "Advanced Options"
    3. then under, "Choose When Updates are Installed" I chose "Semi Annual Channel"
    4. below that under "Pause Updates" I chose "On"

    That turns off Updates for 35 days and only accepts Updates afterwards that are ready for everyone - not just we few beta testers.

    Thank you so much. After working with this for a week, I was finally able to successfully install updates, although I still had to manually download. They did not automatically download after your suggested settings and several restarts. But I've got them and again, thanks. My only question is, should these settings be set back to default, or left the way they are. Windows update default is manual (trigger start) and trusted installer is manual. Has anyone had any new updates since making these setting changes?

    JPzapa thank you very much. Your advice worked for me, after a week of trying everything else.

    " In English, open CMD as administrator, an type one by one:

    SC config wuauserv start= auto [Press Enter]

    SC config bits start= auto [Press Enter]

    SC config cryptsvc start= auto [Press Enter]

    SC config trustedinstaller start= auto [Press Enter] "
