Windows 10: Task Scheduler - All Tasks History disabled

Hi, one of my clients has reported that All Tasks History in the task scheduler had been disabled, and that he wanted to know who had done it. I've determined the exact date and time when this occurred, but the logon logs for then have been turned over and I no longer have access to them, so I can't try to deduce it that way. I've been googling around without being able to find the answer - does Windows keep a log for disabling of All Tasks History? Thank you

:)

 

Schedule task not repeating.

In Task Scheduler, Enable All Tasks History

If history is enabled you can look at the History tab of any task that ran since history was enabled to see each step in the task
Look at each step in the task and see if there are any errors

I don't know if there is a tutorial for this with pictures and better instructions, i couldn't find one

 

No permission to disable a task in Task Scheduler

You keep talking about a "folder". Task scheduler items are files, not
folders, even though they have no name extension (i.e. no full stop or anything else to the right of the name).

I suspect the task is protected through its entry in the registry. You need to open the registry editor (regedit.exe), then do this:

• Navigate to this key:
  
  HKLM\SOFTWARE\Microsoft\Windows NT\Current Version\Schedule\TaskCache\Tasks\
• Find "UpdateOrchestrator", using Ctrl+F. It will be against a key such as
  
  {AB62362D-3EF5-4BD4-92E1-D96143FD8738}
• Change the owner of the key to "Administrators"
• Grant full access to "Administrators".
  

You then need to take the same four steps with this key:

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

 

Task Scheduler History keeps getting disabled

After any significant update in Windows 10, the "All Tasks History" gets disabled in the Task Scheduler. I keep enabling it, and Microsoft keeps disabling it after Windows Updates. How can I stop it from getting disabled?
