    Tiworker.exe, "preparing windows...", system maintenance


    Hi all,

    my Win 10 Pro AU is very new and clean, and installed with the latest update (two days ago).

    Today, I leave alone my pc for a long time.

    When I back I found "WINDOWS MODULES INSTALLER" to 20% of CPU and the system fan very loud.

    I found that is "TiWorker.exe" the cause.

    I also found that the "System maintenance" was ON (I see it in the event viewer).

    So I reboot my PC and appeared "PREPARING WINDOWS. DO NOT SHUTDOWN".

    I waited for minutes, ten, twelve, etc, so I bore and I turn off from button.

    What's happened??? I am almost sure it's related to system maintenance... can be?

    Hello, powering down is almost the worst thing you could do here, as you could now have corrupt files on your disk. It did say not to.

    If your PC will restart and boot up correctly, this is the recommended advice:
    TiWorker.exe: CPU usage reaches 50% or 100% in Windows 10| Fix TiWorker issue

    If CPU use is very high or you experience heating issues, to limit this (you shouldn't need to) you can download and run this:
    BES, Battle Encoder Shirase 1.6.2 (stable) 1.7.0-alpha: Controls Per-Process CPU Usage

    If you search the web about this, you will find some dangerous pages and some genuine ones. Be careful.
    and configure it to limit the CPU load of this process.

    I've not seen this in Win 10 personally.

    Meanwhile, please complete your system specs:
    System Specs - Fill in at Ten Forums - Windows 10 Forums

    and give it an hour, then see if it has stopped running.
    If not, please post back.

    This offers some useful ideas:

    When it has, as you've powered off, do this:
    From an admin command prompt
    [Windows key + X, click command prompt (admin)]
    chkdsk C: /F
    Your PC will need to restart.
    Make sure the result is clear or fixed- else do not proceed.
    Post back the result, which you can get after a restart as follows:

    I have never seen it before, until yesterday. Same effect observed on all (3) my machines. Related to the last updates? And my PC's donot have yet the anniversary upgrade. After long waiting everything became normal again.

    Normally, yes. When you install updates TIWorker tidies up your WinSxS directory (where all your Windows software is). Let it finish.
