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 wonder if you are on the same version of Windows?  The other possibility is that the other people responding tried to copy and paste rather than typing "start=auto" with no spaces...

    Nope. Does NOT work for me.

    I have 5 desktops and 3 laptops in our home all running Windows 10 home. 2 laptops and 2 of the desktops all have this problem currently.

    If I try to enter any of the commands in the instructions that many ppl say are working I simply get an error message:

    A positional parameter cannot be found that accepts argument 'start= auto'

    Please realize I HAVE read this entire thread and several ppl have pointed out that the syntax must be correct for the start= auto portion.

    I have entered it every way possible. No spaces whatsoever before and after the equal sign, spaces before AND after the equal sign and a space before OR after the equal sign.

    All variations produce the same basic error but with whatever syntax variation I used in the error message.

    I am logged into windows as an Administrator and have verified my Administrator privileges. I also chose the Windows Power Shell with Administrator privileges.

    It reminds me so very completely of an old auto-update snafu we had with Windows Vista not too long after its release. Frustrating.

    Please message me or email me if you are reading this and find a solution to this.

    Thanks,

    @NeuroShock  I've had similar "issues" and believe the problem is that the instructions posted earlier were for Windows 8.1, not the latest Windows 10.  One of the unfortunate aspects of the way Microsoft has maintained their forums is that there are a lot of people who tend to ignore the context of a specific post.  When threads get as long is this one, it can be a PITA
