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:
SC config wuauserv start= auto
SC config bits start= auto
SC config cryptsvc start= auto
SC config trustedinstaller start= auto
I tried this and restarted. It went through a two-stage update and turned back on, but my update history still says that the update has failed. Is there another way to get the update to work?

My experience was that the SC Config settings did not completely fix the problem and I still had some multiple failures to install and the Awaiting Restart loop.
I uninstalled as many of the existing updates that I could (some do not have the uninstall option) and then started over with the latest updates.
Best to Create a System Image first in case things go wrong.
Take a look at my post of March 20^th^ on page 11 of this thread.

With the same code? If so, you will need to dig into the diagnostics to find what is really failing. As I indicated if it is during an "apply" phase our tools are unclear. Maybe you would get something in the Windows Error Reporting section of the msinfo32 tool. E.g. I don't think it would be in either ReportingEvents.log or even WindowsUpdate.log but it might be in a piece of CBS log (probably not the most current piece). Otherwise it would probably be in some (unclear) Events log. What I have suggested people can try in this case is simply find out what has changed and list the files in that order. Then depending on when that was (especially in the case of a CBS log) you will have to be wary about whether you are looking at clues from failures that happened during a rollback. E.g. unless you can simply stop a rollback (perhaps with a boot menu) and look at the diagnostics then you need to be aware that common files won't be related to just the issue that caused it.

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 for the tip, this worked for me, it took 2 to 3 MS stating it is updating my laptop and then a couple of days later all is good.
