The Task Scheduler schedules and coordinates tasks at run time. A task is a unit of work that performs a specific job. The Task Scheduler manages the details that are related to efficiently scheduling tasks on computers that have multiple computing resources.
Windows OS provides a preemptive kernel-mode scheduler, it’s a round-robin, priority-based mechanism that gives every task exclusive access to a computing resource for a given time period, and then switches to another task.Although this mechanism provides fairness (every thread makes forward progress), it comes at some cost of efficiency.For example, many computation-intensive algorithms do not require fairness. Instead, it is important that related tasks finish in the least overall time. Cooperative scheduling enables an application to more efficiently schedule work.
