Getting error 0x80070BC2 doing Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4056892)

PLEASE FIX THIS.  This update has failed over 20 times.

Surely at least one Microsoft employee is smart enough to fix this problem.  A simple call to any of the people suffering from the problem would allow this one employee to see what's wrong.

EXTREMELY UNHAPPY.

Hi

open CMD as administrator, an type one by one:

SC config wuauserv start= auto [Press Enter]

SC config bits start= auto [Press Enter]

SC config cryptsvc start= auto [Press Enter]

SC config trustedinstaller start= auto [Press Enter]

reboot system

Hope this helps!

This is the fix!  Anyone having this annoying issue just do as the quoted instructions post and no more problem.

Thanks for the info!  Fixed same issue on two different clients by only setting the Windows Modules Installer service (trustedinstaller) to automatic and restarting immediately. No need to change the default startup behavior of the other listed services.

Could this issue be related to this?

The TrustedInstaller service changes the default service startup type of Manual (3) to Automatic (2), when it encounters an update that has to process a transaction after a restart.   When the value is set back to Manual before the restart the transaction that has to be applied after restart cannot be applied.  This transaction will be pended. It will block all other update installations that might come up.

And that is really old.. from Vista!  

Don't see how is MS going to fix this without manual intervention from the user, cause this issue blocks all the newer update installations, if that's the related issue.

The problem can be solved by

open CMD as administrator, an type one by one:

SC config wuauserv start= auto [Press Enter]

SC config bits start= auto [Press Enter]

SC config cryptsvc start= auto [Press Enter]

SC config trustedinstaller start= auto [Press Enter]

reboot system

Hope this helps!

How do I reverse this? After following these instructions, my machine won't boot.

This worked great for me! thanks!

I have a message which says this has been tried 38 times, now says my computer is at risk as security updates are not being loaded. Have tried all the tests including some already suggested here, isn,t it time this was sorted out by Micrsoft.
