% Total Privileged Time is the average percentage of non-idle time all processors spend in privileged (kernel) mode.  It is the sum of Processor: % Privileged Time for all processors on the computer, divided by the number of processors.  System: % Total User Time and System: % Total Privileged Time sum to % Total Processor Time, but not always to 100%.  (Privileged mode is an processing mode designed for operating system components which allows direct access to hardware and all memory.  The operating system switches application threads to privileged mode to access operating system services.  The alternative, user mode, is a restricted processing mode designed for applications and environment subsystems). This counter displays the average busy time as a percentage of the sample time.
