    No permission to disable a task in Task Scheduler


    Hello,

    I'm trying to disable a task in Task Scheduler, FCU 1709 as I always did with all previous versions of W 10 without problems.
    Now, when I go to Task Scheduler/Microsoft/Windows/Update Orchestrator/Scheduled Scan and trying to disable that task, I'm getting the message:

    "The user account you are operating under does not have permission to disable this task" .

    I'm using an administrator account.
    I found a similar thread but it does not work: https://answers.microsoft.com/en-us/...f-c9b1687ae797

    Please let me know how to solve this problem, because this task makes run Windows Update at boot, and when I do not use, for a while, one of my W 10 systems (W 10 Home), I do not want Windows to install, at boot, Windows updates before I run wushowhide utility and hide unwanted updates.
    I hope this change/issue, which first appeared with FCU version 1709, is not hardcoded in order to prevent this task from being disabled.
    Thank you.

    I get the same message in build 17046.

    If you haven't already, you might enable the built-in Administrator account, sign in to that account, and see if it may be able to disable the task.

    Hi,

    Already tried, no joy!!!
    I also tried regedit and gave for some related keys full control to Administrators, no luck at all!!
    This is the executable which this task enables.

    This has been blocked since 1709. MS does not want people disabling WU.

    You can disable auto-checking for updates, like this:
    Code:
    takeown /f "%WINDIR%\System32\UsoClient.exe" /a
    icacls "%WINDIR%\System32\UsoClient.exe" /remove "Administrators" "Authenticated Users" "Users" "System"
    .

    Thank you for your reply,
    Am I supposed to run those 2 lines, from an elevated cmd, one by one?
    Also, after running this, will I be able to disable Task Scheduler/Microsoft/Windows/Update Orchestrator/Scheduled Scan task in Task Scheduler?

    Cheers,

    Should not change ownership or modify system file. Just download ExecTI
    run as shown below, should be able to disable:

    Sorry for the late reply, been very busy, I tried both methods, first method didn't work, task cannot be disabled and running at boot.
    I also tried ExecTI, BUT there is a problem, I opened Task Scheduler with ExecTI, the Scheduled Scan task could be disabled but with side-effects, it's impossible to re-enable that task, W 10 throws error messages and also if I open Task Scheduler with normal Admin account it also shows error messages.
    I tried another "tweak" that seems to work fine.
    I opened regedit.exe and located: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Update Orchestrator\Scheduled Scan and backed up that key, then deleted and reboot.
    After reboot ran Dism Online it came back clean, then sfc /verifyonly also came back clean.
    Event Viewer does not produce any errors, manual Windows Update scan works fine and the Scheduled Scan task does not run at boot.
    The deletion of the registry key is totally reversible, if I restore the key, Scheduled Scan task appears back again in Task Scheduler with default settings and running ok.
    Will test a few days more and report back.
    So far, Event Viewer is error free, I would like however, any comments from the Gurus here.
    Thank you.

    Permissions of SYSTEM (neither Admin nor TrustedInstaller) are probably needed.
    - download & unzip pstools from sysinternals
    - run psexec -i -d -s mmc taskschd.msc
    - enjoy

    No. That Update Orchestrator service is svchost.exe -k netsvcs.

    The Update Orchestrator in Task Scheduler is usoclient.exe.

    Anyhow, the same scheduled task reported by Vaio 7 up there in #1 is also giving me fits.

    The two Update Orchestrator items Schedule Scan and Schedule Retry Scan since the 1709 upgrade have been bringing my Win10 Home system out of hibernation (discovered via powercfg /waketimers). While these didn't exist in 1703 or if they did (I don't remember) I had them disabled and 1709 enabled them. And I can verify the built-in admin account has not the permissions to disable them.

    (FYI: Those two scan items do not appear in my Win10 Pro system Update Orchestrator. I hate Win10 Home with the passion of a 1000 burning suns.)

    I've been using shutdown instead of hibernate as a workaround for the unwanted wake ups.

    Extensive research reveals mostly that folks have been stumped but this just showed up yesterday:

    Allow only manual updates on Windows 10 - gHacks Tech News

    Yes, this does expand on TairikuOkami's #4 post with useful embellishments, like a set of instructions. And... pictures!

    I can't get to this until the weekend, so maybe an astute tenforums member or two might want to try it and report if that allows the Schedule item(s) to be disabled.

    Cheers.
