Solution

The correct answer is 16 non-real-time priorities.

Key Points

• Windows scheduling uses a priority-driven, preemptive scheduling algorithm.
• In Windows operating systems, there are 16 different priority levels for non-real-time tasks.
• These priority levels range from 0 (lowest priority) to 15 (highest priority).
• Tasks are assigned a priority level, and the scheduler selects the task with the highest priority to run next.
