This counter reports total page faults across all process working sets, as tracked within the general System statistics group alongside CPU and process metrics. Having this counter in the System group lets an admin correlate paging activity directly with process count and CPU busy time from a single summary source without cross-referencing the separate Page statistics group. For example, if this counter accelerates at the same time the system's overall process count jumps, the admin can attribute the extra faulting to newly-started processes building up their working sets.
