Running applications or programs at this priority level can easily crash your computer. For this reason, this level is only reserved for hardware interface processes. Essentially, tasks at this level run in real time, at the expense of any other process.

Real time - This is the highest possible priority level in Windows 11.

This priority level is NOT recommended for user applications.

High: is the priority level used for important system processes necessary for the proper functioning of the computer.

This process level is used for tasks that need a little boost, but without impacting system processes.

Above Normal - This is the next priority level.

Normal: Most applications run at this level.

Best suited for unimportant tasks without time constraints. Processes at this level are allocated fewer resources than normal applications.

Below normal: This priority level just below normal.

Tasks that operate at this level receive resources only after all other processes have completed their current tasks.

Low: This is the lowest priority level in Windows 11.

Specifically Windows 11 can grant up to a total of 6 priorities to the tasks or processes that are running: Windows 11 has several levels of priorities. This helps to ensure that even when your computer is running near peak performance, your PC's core capabilities and operating system are not affected. In this way, the tasks that are essential for the proper functioning of the computer (mainly operating system processes), are given a higher priority, which causes the program / task to be displayed at the top of the list. The OS chooses the execution of different processes and tasks based on a priority assigned to each of them since the priority of the process is simply the 'importance' of each process. The Windows 11 operating system enables multiple background tasks and services to be performed simultaneously.
