What tool can be utilized to track the percentage of system resources currently in use?

The tool used to track the percentage of system resources currently in use is performance monitor, known as perfmon.exe. This application allows users to monitor various performance metrics for the operating system, hardware, and applications. It provides detailed graphs and data regarding CPU usage, memory consumption, disk activity, and network utilization, enabling system administrators and users to analyze the performance of their systems in real time.

By using perfmon.exe, you can add specific counters that track resource utilization over time, helping identify trends and potential bottlenecks. This is particularly useful for troubleshooting performance issues, optimizing resources, and maintaining overall system efficiency.

Other tools listed serve different purposes; for example, devmgmt.msc focuses on managing hardware devices, eventvwr.msc is used for viewing event logs that provide insight into system and application events, and systempropertiesadvanced.exe is used to modify system performance settings, such as virtual memory and system restore settings, rather than actively monitoring resource usage.
