System
Performance profiling: a measurement type that indicates a function or procedure that was timed because it is located in a system module.
Coverage monitoring: a coverage type that indicates a function, procedure, or method that was excluded because it is located in a system module.
By default, certain modules in the Windows directories are excluded from coverage monitoring. Some of these modules, known as system modules, are always excluded and you cannot change their coverage level. The coverage level for these modules appears as (System). Modules excluded from coverage do not appear in any data views.
