Task scheduler error

    Question

  • I have a problem with task scheduler.
    I've narrowed it down to the following tasks:
    AD RMS Rights Policy Template Management (Manual)
    SystemSoundsService
    WindowsParentalControls
    WindowsParentalControlsMigration
    Windows Backup Monitor

    The error thrown up is 'The selected task "{0}" no longer exsists. To see the current tasks, click Refresh'

    Once I moved these tasks from C:\Windows\System32\Tasks everything works ok, are these of any importance or can I just delete them?

  • You may also check Registry. All the tasks are stored in the following branch.

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks

    Check if the following tasks related branches are all present.

    AD RMS Rights Policy Template Management (Manual)
    SystemSoundsService
    WindowsParentalControls
    WindowsParentalControlsMigration
    Windows Backup Monitor

    Additionally, check if the tasks are present in the task tree. Please check in the following branch. The structure is the same as it in the folder C:\Windows\System32\Tasks

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft

    Please let us know the result.

  • Check to see if Windows Event Log Service is still working properly in all sections.  The Task Scheduler is dependant on the Windows Event Log Service.  If the WEL is disfuntional in anyway then it could effect the Task Sheduler as well.

  • Everything appears to be working ok with Event Log, just been through event viewer and there was 12 errors associated to Task Scheduler over the last 2 weeks, the event id is 413, and gives this description 'Task Scheduler Service failed to load tasks at service startup. Additional Data: Error Value: 2147549183'
    Scheduled tasks are running as normal, but as soon as I move one of the offending tasks back to the correct folder it stops working again.

  • I am seeing this on a couple of Windows 7 x64 computers. Task {0} is invalid.  Mind you all the task folders that should show tasks; in Task pane are empty.

    Could this be due to a Windows update?

    I do have CCLeaner installed, as well as JKDefrag.

    I have the same installed on a Windows 7 x64 w/o the problem.

    Is there a way to refresh the task scheduler install?  Maybe a new version of the good o'l standby: Dial-A-Fix

    There are no tasks available and the intial Task Scheduler page is empty and shows " Error Reading Data".


    Thanks in advance

  • Looks like CCleaner was the issue.  Make sure you're using a more recent version of CCleaner (post 2009).
