Control Center will allow you to cancel a batch processing task before it starts by deleting it from the queue, but if you delete a batch processing task while it is already processing, it will still finish in the background.
Vectorizing tasks are added to the queue on a per-drawing basis. This means that if you want to interrupt the vectorization of a scene, you can simply stop the batch processing service and clear the queue in Control Center. However, rendering tasks are added to the queue on a per-scene basis. Therefore, the only way to interrupt the rendering of a scene while it is currently rendering is by interrupting the Harmony process that is rendering the scene.
IMPORTANT You should only interrupt a batch processing task when it is necessary, such as when an extremely lengthy task was started by accident and is liable to delay the other tasks.
Press Ctrl + Alt + Del to open the Windows security screen.
Select Task Manager.
If the Task Manager only lists the open applications and has no menu or tabs, select More details at the bottom.
Open the Details tab.
Look for a process named tbprocess.exe.
Right-click on the process and select End process tree.
This will terminate the batch processing daemon (tbprocess.exe) as well as any Harmony process it might have started to render a scene or vectorize drawings. The batch processing daemon should restart instantly, but it will not attempt to process the batch processing task that was interrupted again.
NOTE The job you interrupted will still appear in the queue with the Processing status in Control Center. You will need to delete the job manually from the queue to clear it up.
