task scheduler task deleted by NT AUTHORITY\system- event 141


  • recently rebuilt some tasks in my task scheduler after a windows update caused several tasks to be corrupted.

    all went fine except the task "ConvertLogEntries"

    i successfully added that task, and according to history it ran a few times. then at one point a few days ago it was deleted.
    the history entry says"
    "user NT AUTHORITY\System" deleted task scheduler task ...

    does anyone know why this happened? according to the microsoft help i was able to find, this action and the event code 141 describing it is "normal and not of concern"

    that's a bit confusing to me, as i don't see why that particular task would just be automatically deleted for "normal" reasons.
    the task was present before the scheduler became corrupted and had to be fixed, so i assume it should be in there.

    any help?

  • Hi,


    This issue may be caused by certain programs running in the background.


    What about to restart the computer to check?


    What about to disable the third party security programs and boot in Clean Boot to check if the issue persists?


    Also, please provide the detailed event log for our further research:


    ·         Event Log


    1. Click "Start", input "eventvwr" (without quotation marks) in the Search bar and press Enter.

    2. Right click on "Application" on the left frame, choose "Save Log file As"; in the pop-up window, click to choose the Desktop icon on the left frame, input "app" in the "File name" blank, and then click “Save”.

    3. Right click on "System", with the same method, save it as "sys".

    4. Locate the two saved log files on the Desktop and send them to us.
