We couldn't finish installing updates (KB4074588), error 0x80070bc2

Hi.

I'm unable to install the latest windows update 2018-02 Cumulative update for Windows 10 version  1709 for x64-based Systems.

The error is 0x80070bc2

It says updates are available, awaiting restart. When I restart it fails. "We couldn't finish updates.." Then says updates are available, awaiting restart. I restart again and it fails again. Over and over.

I tried using windows update troubleshooter, the tool performed its fixes but it had no effect.

Is there a solution to this?

Thanks

(Update - 2/17 Editing for clarity based on feedback)

If you are currently experiencing the 0x80070bc2 error while attempting to install KB4074588, please try this:

  1. In the search box on the taskbar, type cmd.
  2. Right-click Command Prompt in the search results and select Run as administrator.  (Select Yes, when prompted by the User Account Control.)
  3. In the Administrator: Command Prompt window, type the following command and press Enter:

SC config trustedinstaller start=auto 4. Restart the PC.

In some cases, a second restart may be required. If you look under Settings > Update & security and you see the message Status: Awaiting restart, restart the PC a second time to complete the installation.

    Hi, Paul

    Your solution worked out for me fine, thanks.

    I understand that trustedinstaller was changed to "auto". Should I return to command prompt and undo that (set to "manual"??) now that the update was successfully installed?

    Thanks again,

    Dan

    This worked beautifully! Thank you! It restarted and for the first time this morning I had no notices, then it restarted again for part 2 of the update and went to 100% with zero problems! It's been restarted around eight times this morning even during "Active-hours" which apparently don't mean anything. Anyway I am now going to my other computer to see if I need this fix for it, and thanks to you it is just copying a line for the cmd window, so thanks for doing the hard work and letting me know how to actually install this, perfect! Thanks again.
