* Note, these values tries to mimic the outpof of wmic.
*
* If the value is below 4, then the process priority will default to
* NORMAL_PRIORITY_CLASS and anything above 23 will always be
* REALTIME_PRIORITY_CLASS.
*
* This is applied to the main process, not per thread, although this could
* be implemented using SetThreadPriority() at one point.
