Process Monitor vs. Task Manager: Key Differences Windows offers several tools to monitor system activity, but Process Monitor (ProcMon) and Task Manager serve entirely different purposes. Task Manager provides a quick, high-level overview of system health. Process Monitor offers a real-time, granular look at system events. Understanding their differences helps you choose the right tool for troubleshooting. Core Purpose
