How to Monitor Windows System Resources

If your computer is running slower than usual, experiencing lags, or applications are freezing, it might be time to check what resources are being used and find ways to optimize performance. This guide covers the main methods for monitoring system resources like CPU, memory, disk, and network in Windows.

1. Task Manager

Task Manager is a built-in Windows tool that provides a quick overview of system resources. To open it, press Ctrl + Shift + Esc or right-click the taskbar and select "Task Manager".

  • In the “Processes” tab, you can see which apps and processes are consuming CPU, memory, and disk resources.
  • The “Performance” tab displays real-time graphs of resource usage.
  • The “Network” section shows current network activity and data transfer speeds.

2. Resource Monitor

Resource Monitor offers more detailed insights into system processes and their impact on resources. To open it:

Press Win + R, type resmon, and hit Enter.

In Resource Monitor, you can check:

  • CPU: Graphs showing CPU usage and specific processes utilizing CPU time.
  • Memory: Detailed information on RAM usage by each process.
  • Disk: Analysis of read and write activity on your disks.
  • Network: Monitoring network activity, including which processes are consuming bandwidth.

3. Device Manager

If you encounter hardware issues, Device Manager can help you identify driver problems. To open it, use:

Win + X → Device Manager

Here, you can check the status of your hardware drivers and update them if necessary.

4. Performance Monitor

Performance Monitor allows you to create detailed reports and charts for resource usage analysis. Open it with the following command:

Win + R → perfmon

You can set up custom data collection and analyze long-term trends in resource usage for deeper insights.

5. Third-Party Tools

For advanced monitoring, you can use third-party utilities such as:

  • HWMonitor — Monitors temperatures, voltages, and other hardware parameters.
  • Speccy — Provides detailed information about all system components.
  • Sysinternals Suite — A powerful collection of utilities for diagnostics and monitoring.
