By regularly using Windows 10, one can easily understand that the operating system is a mixture of various background tasks and processes. Now, to complete a lot of background processes, Windows uses a Task scheduler. The basic job of the Task Scheduler is to manage, plan and align tasks according to priority. In this article, we cover some basic and useful steps to correct the Task scheduler not run problem in Windows 10.
Task scheduler
The Task Scheduler is used by the operating system to plan all the background processes, launch applications and manage them. The method used behind is that the scheduler calculates all the resources necessary for any process to complete. It creates the queue of these processes according to their needs and their priority. When everything is set, all tasks are then sent to the processor for execution. It operates on the basis of time and memory consumption. In addition, anyone can create and schedule their own tasks.
You may have already understood that the proper functioning of the Task Scheduler is a necessity. If you are experiencing some error because the Task Scheduler is not working, this may be a problem for you. This is because of all your background tasks, the current tasks and the upcoming tasks collide and make your machine freeze again and again.
Now let’s see why it doesn’t work and what may be the possible method to fix the problem.
