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 have this exact same problem.

    However, even with the command line open as administrator, I can't rename those two directories: "Access Denied".

    Even the Windows Update Troubleshooter says everything fixed but to no avail.

    Very frustrating.

    What I might do next is open command prompt (admin) and paste the lot of commands in;

    net stop wuauserv

    net stop cryptSvc

    net stop bits

    net stop msiserver

    Del C:\ProgramData\Microsoft\Network\Downloader\qmgr*.dat

    Ren C:\Windows\SoftwareDistribution SoftwareDistribution.bak

    Ren C:\Windows\system32\catroot2 catroot2.bak

    Then later on after reboot  and all seems well delete folders;

    SoftwareDistribution.bak

    catroot2.bak
