SetPriorityClass

SetPriorityClass is a function in the Windows API that allows a process to set the priority class of itself or another process. The priority class determines the scheduling priorities of the threads that belong to the process. There are six priority classes available: real-time, high, above normal, normal, below normal, and idle. The real-time class has the highest priority, while the idle class has the lowest. Setting the priority class of a process can affect its performance and responsiveness, as well as the performance of other processes running on the system. It is important to use this function carefully, as setting a process to a high priority class can starve other processes of CPU time, leading to system instability. The SetPriorityClass function is typically used by system administrators and developers to optimize the performance of specific applications or to troubleshoot performance issues. It is not recommended to use this function in user applications, as it can have unintended consequences on system performance.
