  • Since the issue occurs in Safe Mode, I suspect that a system task is lost or corrupt. If you would like to repair the system, launch the Windows 7 installation program in the current system and run Upgrade to perform In-place Upgrade. After doing so the system will be repaired. Generally your personal data will not be lost. However I still suggest you backup important data before In-place Upgrade.

  • If you disabled the Disk Defrag Schedule, then go back and enable it.  If that doesn't work, then what does it do in Safe Mode if you load that for a test run?

    If it is OK in Safe Mode, see if you can isolate some other cause for the problem.

    If you cannot tie the problem down to another process, see if you can reproduce it while logged in as another user.
    Let's check to make sure the service is set to run automatically. 

    • Click the Start orb
    • In the Start Search box, type services and press enter.
    • Scroll down to Task Scheduler, right click it and choose properties. 

     

    Make sure the start up type is set to Automatic

    Restart your PC and see if you get the error again.

  • nope - service is running fine and is set to automatic; problem persists under safe mode too

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache differed from C:\Windows\System32\Tasks which is why error will occur until both are in sync by the looks of it

  • I had a clean install of Windows 7 Professional, and encountered this error "The selected task {0} no longer exists" after roughly two (2) weeks. I have tried all the suggestions up to and including an "In-place Upgrade" and the problem is still there. I have no special programs installed and no user defined tasks scheduled. I performed an additional clean install and all was fine for another two (2) weeks and same issue appears. Any thoughts?
