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.

    Hello Steve,

    Brilliant.........Well done........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. Thanks mate........I am truly grateful for this great 'fix'.

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