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.

    I followed the instructions and the first line gives me this error:

    PS C:\WINDOWS\system32> SC config wuauserv start= auto

    Set-Content : A positional parameter cannot be found that accepts argument 'start='.

    At line:1 char:1

    • SC config wuauserv start= auto 
    •

        + CategoryInfo          : InvalidArgument: (:) [Set-Content], ParameterBindingException

        + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.SetContentCommand

    I have this problem too. 

    The problem is that you are using PowerShell  so if you enter  SC.exe  (not just SC) it should work.

    Alternatively go to   Command Prompt   (under Windows System not PowerShell)  then RIGHT click on Command Prompt  and select Run as administrator.

    Hope this helps.

    I had been attempting to install the update on my tablet for some time and getting the error message.  Suddenly, the update installed itself and so did the later one. It seems that something had been tweaked to enable the update to work.  Just shows, patience is a virtue after all!

    These commands do not work for me. I typed them 

    exactly as I see them.
