The main culprit behind the Task Scheduler failed to start - Event ID 101 on Windows 11/10 client machine or Windows Server is permissions-related. The simplest fix is to add the user to the "Log on as a batch job" property on the respective server or client machine. Follow these steps:

  • In the Properties window, click the Add User or Group button to add the appropriate username to the group.

Set Task Scheduler service to Automatic

The issue you're facing might be due to the Task Scheduler service being disabled, not running, or not set to automatic startup (the default setting). To rule out this possibility, follow these steps:

  • Press Windows key + R to invoke the Run dialog.
  • In the Run dialog box, type services.msc and hit Enter to open Services.
  • In the Services window, scroll and locate the Task Scheduler service.
  • Double-click on the entry to edit its properties.
  • In the properties window, click the drop-down on Startup type and select Automatic.
  • Make sure the service is started by clicking the Start button (if not grayed out).

  • Restart your PC.
