Fix The select task “{0}” no longer exists error in Windows 10

If you are going to use the Task Scheduler in Windows 10, then it might be possible that you face the error message “The selected task “{0}” no longer exists. To see the current task, click Refresh.” And, if you tried to refresh, this message will come again sometimes. This is because the Task Scheduler has a copy of tasks in Registry Editor and another copy of them in the task files on disk.

In Registry, the task is stored in the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks

And the Task tree is stored in:

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

Task File Stored on the disk: C:\Windows\System32\Tasks\

So, this error generally occurs when the tasks in both of the above location are not synced which means either the task of Registry got corrupted or the task files on the disk got corrupted. So, in this article, I am going to provide you two simple methods for fixing this error.

Before starting the procedure, make sure tojust in case something goes wrong. And also, take the backup of Registry.

Methods to Fix The select task “{0}” no longer exists error

Method 1: Repair Task Scheduler by Deleting Corrupted Tasks

As the corrupted files cause big problems, deleting them is very important. To delete a corrupted task or any task from Task Scheduler, you need to take the help of the Registry Editor. As we don’t know the name of the task, so we are taking the example of Adobe Acrobat Update Task which in this case is generating the above error. So, let’s start with the steps.

Step 1: Press Windows Key + R then type regedit and hit Enter to open Registry Editor.

Step 2: Now, navigate to the following path in the Registry Editor:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\Schedule\TaskCache\Tree\

Step 3: Find the Adobe Acrobat Update Task under the Tree key, then from the right side of the window double-click on ID. See the image below for reference.

Step 4: After completing the above step, now you have to note down the GUID string. In this example, it is {048DE1AC-8251-4818-8E59-069DE9A37F14}.

Step 5: Right Click on the Acrobat Update Task and select Delete.

Step 6: Now, delete the same ID which you have copied in Step 4 from the following folders:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Boot

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Logon

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Maintenance

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Plain

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks

It is not necessary that you find the ID in all the folders. If you find it, delete it. The above image will be helpful to you.

Step 7: Now, navigate to the following path:


Step 8: Delete the same task you deleted from Registry Editor.

Finally, restart your PC to save the changes you have made and see if you’re able to Fix The select task “{0}” no longer exists error. If the problem exists, try out the next method.

Method 2: Manually Sync Task in Explorer and Registry Editor

If there is any problem in the synchronization between Explorer and Registry Editor, you might get this error message while opening Task Scheduler on Windows 10/8/7. You can try synchronizing them manually. So, follow these steps carefully to solve the error.

Step 1: First, navigate to the path: C:\Windows\System32\Tasks

Step 2: Now, open the Registry Editor and navigate to the following registry key:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\

Step 3: After completing the above step, now you have to one by one copy the name of the Tasks from C:\Windows\System32\Tasks and search for these Tasks in the registry subkey \TaskCache\Task and \TaskCache\Tree.

Step 4: If you find any extra task in either location, you can delete that task and then check whether Task Scheduler is opening properly or not.

By completing the above steps, you will sync all the task in Registry Editor and Task folder. Now, reboot your system to save the changes and your problem is now solved.
