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 tried the fix with command line and it still says awaiting restart and doesn't show as installed in control panel.  I had a microsoft technician tell me my laptop isn't compatible with the update but that didn't sound right to me.  Any ideas?

    yes the only way to solve it is to do a reinstall,id a tek bloke come on mine he tried everything he knew told me windows update had stopped working,id tried to 30 times to update it and run all the trouble shooters Microsoft had even went into command prompt and run the dism and sfc scan nothing,i even tried to download it manually nothing.he was on here 1.40mins problem solved with a reinstall.

    This worked for me.  My ASUS Zenbook was caught in the restart loop due to the failed update install, but following this process the update finally successfully installed.  Hopefully all is well now (he said, tongue in cheek...)
