Task Scheduler not running

Task Scheduler helps with scheduling (the same way you schedule jobs) programs, and scripts, and one of the scripting languages it is used on is Python.

Many users claimed that when it isn’t working, the Python script in Windows 10 cannot be launched at the times or intervals as planned.

Before resolving the issue, check the last time it worked, and whether you made any recent hardware and/or software changes on your computer.

Here are some helpful solutions to help you fix the Task Scheduler if it’s not running the Python script, so keep reading!

Particular troubleshooting steps on Task Scheduler

1. A task doesn’t run as and when it is expected to

If this happens, ensure the task is enabled, and check that the triggers on the task are set correctly. Check the task’s history to see when it was started and check for errors.

A task only runs if its conditions are met. Some run when a particular user is logged in depending on the security options on the task itself, so ensure the task’s security options are correctly set.

2. The task runs, but the program didn’t run correctly

If this happens, try running the program manually (not from the task) to check that it works properly. You can add a command line option to the program’s path.

Some programs need elevated privileges to run correctly, so set the task to run with the highest privileges by changing its security options on the General tab of the Task Properties dialog box.

If the program doesn’t run properly, check the task’s history for any errors.

3. You get an error when the task tries to send an email

If this happens, and the email isn’t sent correctly, ensure the settings for email action on the task are properly set.

The email action should have a valid value for the SMTP server To and From settings. Ensure the SMTP server is set up correctly.

4. A task uses 100% of the CPU

  1. Restart in Safe Mode (Task Scheduler doesn’t run in Safe Mode).
  2. In Windows/System32/Tasks folder, rename the task file, or delete it.
  3. Restart in Normal Mode.
  4. Redefine the task.

If this occurs, the system can be rendered unusable. Disable the task, then change its trigger. If the system is unresponsive because of this issue, follow the above steps.
