Scheduled tasks fail after installing Fall Creators Update

Question

_{Friday, November 10, 2017 10:37 AM}

I discovered that after installing the Fall Creators Update, some specific tasks in the Task Scheduler started failing when executed.

It happens every time I run an existing task and also when I create a new one and try to run it - the key is to enable "Run whether user is logged on or not" and select "Configure for: Windows Server 2003, Windows XP and Windows 2000". If I change one of these parameters (i.e. choose "Run only when user is logged on" or select a different OS option), the tasks executes normally.

A task with the same options works fine in Windows 10 version 1609, but fails in version 1709. 

More details: 

• when I register a task with these parameters in version 1709, I get a warning logged in history: "Task registered without some triggers". The description is: "Task registered task "\mytask" , but not all specified triggers will start the task. User Action: Ensure all the task triggers are valid as configured. Additional Data: Error Value: 2147942487.".
  The error code apparently means "invalid parameter". I tried it with two kinds of triggers: "One time" and "Daily" - most basic, completely normal and working fine for other tasks, but somehow invalid in this particular configuration. 
• when I run the task (by choosing "Run" in the Task Scheduler), I get a message box with an error: "An error has occurred for task mytask. Error message: The selected task "{0}" no longer exists. To see the current tasks, click Refresh.". The task obviously exists, and the event description logged in history says "Task Scheduler failed to start "\mytask" task for user "(default user)". Additional Data: Error Value: 2147943568.". 

Here are my questions: 

• does anybody know why exactly do these tasks fail to run? 
• will they continue to fail in the future or can I expect this to be fixed?

Hi,

I have checked the issue on my side, but there is not such symptom occur on my Windows 10 1709 device. No matter I choose "run only when use is logged on" or with default setting.

Are there any error messages occur in Event Viewer\Application and service logs\Microsoft\Windows\Task schedule?

Does the issue occur only you configured with the default settings (we need to choose proper Windows version)?

Update your Windows to the latest through Windows update feature, and try to check if the issue occur in Clean Boot environment.

Bests,

Hi,

Any update?

"Task Scheduler failed to start "\mytask" task for user "(default user)"

If it is convenient for you, would you export "my task" and upload to OneDrive then paste the link here?

It would be useful for troubshooting the issue.

Hi

The issue does not occur when the task is configured with the default settings, i.e. the proper Windows version.

The problem that I have tasks that were created a long time ago and configured for older Windows versions, on many machines different than mine. I am not sure if I will be able to access these tasks to edit them and fix the configuration. 

The Event Viewer does not have any error messages beyond the ones I included in my first post. 

To give you a complete picture, here's my task: task

Here's the warning I get at registration: registration

Here's the errors I get when I execute the task: execution1, execution2
