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.

Paul...

    Hi Paul, I did the "SC config trustedinstaller start=auto" thingeny, and my PC restarted suddenly without warning, but then it entered in an endless loop: restarting and trying to install ("don't turn off your computer") and then automatically back to "we couldn't install features, uninstalling the changes" and back again to the restart and trying to install.... After 8 loops I decided to pull the plug and my computer luckily restarted (after a Please wait... message) when I put it back in, but the update still required a restart. I changed the settings to "SC config trustedinstaller start=disabled" (not knowing the setting it really needs) and I'm back at where I started, except that I have to find out what start setting I have to put the trustedinstaller in. For me it did not work.

    Try installing the update manually by downloading from the the Microsoft catalog site here. This worked for a number of our staff.

    Thanks

    I had all of the same problems that you are encountering.  I followed the instructions to the letter and miraculously it worked.
