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.

    Thanks I could do that, since the failed update does not seem to alter performance or give me problems.

    However, this is the second cumulative update that fails in a few days, before I had KB4043961, now KB4048955, both behaving in the way I described, so I wonder if I have some sort of software conflict or other issue and if 0x80070bc2 suggests something or it is just a generic error message.  I mean, I would not wish the inability to update to bring me to a point where I experience real problems.

    If this problem should persist over time, should I try to install a new windows image? 

    I am reluctant to do it now but just asking.

    If the problem persists, then it would be worth trying a repair upgrade.

    Hi,

    The issue may be caused by an improper Windows Update installation. For example, a Windows Update installation interrupted by a crash may result in a corrupted system file. A third-party program conflict can also be the reason for this error.

    Let us narrow down the possibilities why your PC encountered this issue. You can follow the troubleshooting steps below:

    1. Temporarily disable your antivirus program before running the Windows Update.
    2. Visit the article on how to perform a clean boot in Windows. This helps eliminate software conflict that occurs when you install a program or an update. You may also determine what conflict is causing the issue by performing this method.
    3. Fix Windows Update errors. Since you are using Windows 10, you can do this by running the Windows Update Troubleshooter. To download the Windows Update Troubleshooter, click on this link.
    4. Restart your computer for the changes to take effect and try updating Windows again.

    Note: After doing the steps above, you can enable your antivirus program again.

    Keep us posted if you encounter any challenges along the process.
