SeSystemProfilePrivilege gives service privilege to profile system performance.
Allows a user to sample the performance of system processes. This privilege is required by the Performance snap-in only if it is configured to collect data by using Windows Management Instrumentation (WMI).
Default setting: Administrators.
Ordinarily, you do not need this privilege to use the Performance snap-in. However, you do need the privilege if System Monitor is configured to collect data by using Windows Management Instrumentation (WMI).
