The default priority of processes run using Task Scheduler in Windows is below-normal. To be more precise, the default task-priority is 7 which comes under the below-normal process-priority category.

Below-normal priority works fine in most cases since Task Scheduler is primarily meant for running background tasks. But there may be cases where you want to run a normal task or even a task that you want to finish as soon as possible. For instance, I often use Task Scheduler to schedule TV recordings; this is a task which requires higher than normal priority on many computers.
Unfortunately, it is not possible to change the task-priority from within the Task Scheduler GUI. Here is one of the relatively easier ways to change the task-priority. Right click on the task in Task Scheduler and export the task as an XML file.
Modify the element named priority in the XML file to the task-priority you want. For example, you could set priority to 5 for setting normal priority.
Delete the original task from Task Scheduler
Choose the import task option either from right-click menu or actions sidebar to import the task back.
