    Backup / Task Scheduler not working, even after repair


    I noticed that my father's computer hasn't done backup for more than a month.Upon trying a manual backup, it gives the error:
    "Windows could not launch the automatic backup job for the following reason: Element not found. (0x80070490)"


    I googled that and tried the suggestions here:
    http://answers.microsoft.com/en-us/w...8-efb9d65bca39:


    1) Volume shadow copy was not set to auto
    2) sfc /scannow did not help
    3) clean boot did not help


    I also discovered that the last search for available Windows Updates was performed on the same date as the last backup, and nothing since.
    I did a manual Windows Update search, it found and did some updates, installed and rebooted.
    The problems were still there.
    In system recovery, it seems that there are no snapshots from before the windows update from today!



    I then checked the Task Scheduler, which gave an error message.


    I opened MSCONFIG, disabled all non-MS services, all startup items. I disabled the antivirus and disabled its system protection options.
    I redid SFC / scannow (elevated) a couple of times.
    It repaired some things, but still reported errors.


    I checked the system disk from errors (from gui, not chkdsk), nothing found.

    I did dism /online /cleanup-image /restorehealth, with a MS iso file.
    Redid sfc /scannow, no more errors.

    Backup and Task Scheduler still do not work.


    Do we still have options to save this computer from having to do clean reinstall?

    What build is the PC?
    The task scheduler has been broken on Redstone builds for sometime
    If the PC is on the fast ring you may want to wait until the anniversary drop
    Ensure that the task is configured for Windows 10 (see in task scheduler)

    Version 1511, build 10586.420
    AFAIK, this is not a Redstone build.

    I can't. Task Scheduler opens but is then inaccessible due to a pop up notification that will not go away.
    It says "Task Scheduler service is not available. Task Scheduler will attempt to reconnect to it".
    However, task scheduler service IS running. I restarted the service, but no improvement.

    I'm experiencing the exact same problem as the OP! After the (Windows 10 Pro) Anniversary Update, I saw one of my scheduled tasks hadn't been run in a day or so (it needs to every 30 mins). So I tried to run it manually, and it said "Task scheduler service is not available. Task scheduler will try to reconnect to it." Wut?! So, I checked (in Services) whether the Task Scheduler service is even running; and sure enough it is.

    Kinda stumped here. Anyone any ideas?

    Had the same problem to the extent that I thought my machine was totally trashed. Clean rebuild and still the same problem. However, I've now pinned down one cause. The tasks that were not running and generating the error message when I tried to run them manually all had a condition set that they should only run if connected to my home network. Set the condition to Any Network or disable it and things run as expected.

    Bit of a bummer when you only want a back-up program to run when you are connected to your home network drive!

    Hope that gives a work-round for at least one of the AU problems.
