Description: %Privileged Time is the percentage of non-idle processor time spent in privileged mode. (Privileged mode is a processing mode designed for operating system components and hardware-manipulating drivers. It allows direct access to hardware and all memory. The alternative, user mode, is a restricted processing mode designed for applications, environment subsystems, and integral subsystems. The operating system switches application threads to privileged mode to obtain operating system services.) %Privileged Time includes time servicing interrupts and DPCs. A high rate of privileged time might be attributable to a large number of interrupts generated by a failing device.
