2] Check Task Scheduler service

The Task Scheduler service enables you to perform automated tasks on a computer. With this service, you can schedule any program to run at any time or when a specific event occurs. The Task Scheduler monitors the time or event criteria you choose and then executes the task when those criteria are met. So, basically if this service is not started and running, probably got disabled on your device for one reason or the other as the service is by default set to automatic startup – then you are likely be experiencing the issue in view.

To check and make sure Task Scheduler service is started and running, do the following:

• Make sure you’re logged in as an administrator on your Windows 11/10 PC.
• 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 the Startup type and select Automatic.
• Next, make sure the service is started by clicking the Start button if not greyed out.
• Click Apply > OK to save changes.

3] Assign proper permissions to the Task

As already pointed out, this error could as well be permissions-related. In Task Scheduler, there is a security option to use a specific group to run the task. So, if the Task doesn’t have the correct permission, you will get this error.

To assign proper permissions to the Task, you need to change the group to SYSTEM to elevate the permissions for the task. To do this, follow the instructions below:

• Press Windows key + R keys to invoke the Run dialog.
• In the Run dialog box, type taskschd.msc and hit Enter to open Task Scheduler.
• In the left pane of Task Scheduler, expand the Task Scheduler Library.
• Now, select the folder that contains the task triggering the error.
• In the middle pane of the opened folder, right-click the task and select Properties.
• On the task Properties window, click General tab.
• Under Security options, click on Change User or Group.
• In the Select User or Group dialog, click Advanced.
• In the Advanced window, click Find now and from the usernames listed select SYSTEM.
• Click OK.
• Click OK again to successfully add the username to the specified task.
• Now, check the Run whether user is logged on or not option.
• Click OK to save changes.
• Reboot your PC.

4] Create new User Account

Before you try this to rule out the possibility of a corrupted profile/account which will potentially prevent the logged-on user from performing certain tasks, you can delete the scheduled task and then recreate the task and see if the task can now run as scheduled. Otherwise, simply create a new local user or administrator account, log into the new account, create the task again. if the task successfully runs under this new account, you can transfer your files/data from the old account to the new account.

If this isn’t the case, but the issue at hand is still not resolved, you can try the next solution.

5] Perform System Restore

As a last resort, assuming the task was running earlier without issues, it’s likely some changes has been made on your system like system update. driver or software update which may have broken the Task Scheduler functionality, consequently preventing tasks from running as scheduled. In this case, an applicable solution is to perform System Restore to revert your system to the certain period you are sure the task was running normally.

That’s it!
