'''Windows NT processor scheduling''' refers to the process by which [[Windows NT]] determines which job (task) should be run on the [[Central processing unit|computer processor]] at which time. Without scheduling, the processor would give attention to jobs based on when they arrived in the queue, which is usually not optimal. As part of the scheduling, the processor gives a priority level to different processes running on the machine. When two processes are requesting service at the same time, the processor performs the jobs for the one with the higher priority.

These levels have associated numbers with them. [[Application software | Applications]] start at a base priority level of eight. The system dynamically adjusts the priority level to give all applications access to the processor.

Priority levels 0 - 15 are used by dynamic applications. Priority levels 16- 31 are reserved for real-time applications.
