Must-Know CMD Commands for Monitoring Windows System Performance
Hello everyone! If you've ever felt your computer slowing down or acting strangely, you've probably wondered what's going on under the hood. 💻 CMD, or Command Prompt, is a powerful built-in tool in Windows that many overlook. But did you know you can monitor system performance, memory usage, and even troubleshoot issues using just a few simple commands? In this post, I'll walk you through some essential CMD commands that can help you keep your system running smoothly. Let's dive in!
1. Why Monitor System Performance with CMD?

4. Real-World Use Cases and Scenarios
Still not sure when you might need these commands? Here are some practical examples:
- Slow PC? Use
wmic cpu get loadpercentageandsysteminfoto diagnose CPU or RAM overload. - Network issues? Use
netstat -eto check incoming/outgoing traffic patterns. - Random crashes?
perfmon /reporthelps identify driver or disk issues. - IT admin? Automate daily checks using
logmanandtypeperf. - Checking hardware before resale? Confirm system specs and health with
systeminfoandchkdsk.
By incorporating these commands into your routine, you'll be more informed and ready to troubleshoot without third-party tools.
5. CMD vs Other Monitoring Tools
There are many tools available for system monitoring, including Task Manager, Resource Monitor, and third-party solutions. Here's how CMD stacks up:
| Feature | CMD | Task Manager | Third-Party Tools |
|---|---|---|---|
| Lightweight | ✔ | ✔ | ✘ |
| Customizable | ✔ | ✘ | ✔ |
| Script Automation | ✔ | ✘ | ✔ |
| Real-Time Stats | Partial | ✔ | ✔ |
