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.

    I know it's been a while now since that update first attempted to install but, if there's a possibility of being able to do what I did to fix mine.. Using System Restore to get back before the failed install, and installing that one manually ..then waiting a few days before letting it do the others again.. it fixed mine and I was never so relieved.. Could work for you if you have a Restore Point from before it all began...

    Hope that helps ya.

    Paul,

    I applied the fix and it did seem to have installed update KB4089848 (I can see it now in Control Planel/Programs/Programs & Features/Installed Updates) however when I look at the update history under Settings it continues to say "Requires a restart to finish installing". Same message appears after each restart. Same issue with KB4088776 and  KB4074588. I tried the Windows Troubleshooter which says: "Potential Windows Update database error detected". Any idea what to do?
