    Up until last February, I didn’t have any trouble with Windows Updates installing automatically. But since,then, one particular update keeps nagging me to restart in order to install it. However, on restarting it tells me it couldn’t install it:
    • 2018-02 Cumulative update for Windows 10 Version 1709 for systems based on x64 (KB4074588)

    In Update history it says:
    Requires a restart to finish installing
    Error code: 0x80070bc2
    (I looked it up but could see no solution)

    So I downloaded the update and tried to install it manually, but got the message that it is already installed.

    The remaining updates continue to install automatically.

    I've opened the Event Viewer, but I can’t make much sense of it.

    Can someone advise what is happening and how to get out of this vicious circle that keeps nagging (and bugging) me?

    Boot into safe mode and delete the entire "C:\Windows\SoftwareDistribution" folder and boot into normal mode and run WU to check (it's a low tech dirty trick that solves many WU problems) :)

    Thanks Enthousiast for responding with advice. I could delete the folder with admin rights without going into safe mode.

    Well, it worked and it didn't. I didn't get notification for KB4074588 this time, but a new update KB4093112 tried to install but gave the same failure notification and error code, namely 0x80070bc2.

    So I googled and found the following fix:
    In the Admin Command Prompt, enter:
    SC config trustedinstaller start=auto
    Reboot.

    It took some time updating, but now the KB4093112 shows installed and the PC up to date.

    As I don’t quite understand the above, can someone answer the following:
    1 What exactly does the command do?
    2 Are there any undesirable side effects?
    3 Should I now bring back the PC to what it was with a new command (which?) or will it do it on its own?

    The command (SC mean Service Control or similar) just sets the TrustedInstaller service to Auto start. No bad effects to expect.

    Thanks Carlos Detweiller.

    The thread can now be closed. It doesn't allow me to edit the title and add SOLVED.
