How to Check Computer CPU Utilization

CPU usage is an important indicator of how active a computer's processor is. It tells us how busy the CPU is performing tasks and whether the system requires additional processor resources. By looking at CPU usage, we can identify system bottlenecks, optimize performance, and resolve potential issues.

So, how do we check the CPU usage? Below I will introduce several commonly used methods.

1. Use the Task Manager that comes with the Windows system
   In the Windows system, the Task Manager is a commonly used system monitoring tool. It provides real-time system resource usage, including CPU usage. To view the CPU usage, you can press the "Ctrl Alt Delete" key to open the Task Manager, and then click the "Performance" tab to see the current CPU usage curve and percentage.
2. Use the Windows command line tool WMIC
   WMIC is the abbreviation of Windows Management Instrumentation Command-line, which can view system information in real time through the command line. To check the CPU usage, press the "Win R" key combination to open the run dialog box, and then enter "cmd" to open the command prompt window. Enter "wmic cpu get loadpercentage" in the window and press the Enter key to get the current CPU usage percentage.
3. Use the top command that comes with the Linux system
   In the Linux system, the top command is a very powerful system monitoring tool. It provides a real-time view of system resource usage, including CPU usage. To check the CPU usage, enter the "top" command in the terminal and press the Enter key. In the top interface, press the "Shift P" key to sort by CPU usage to find the processes currently occupying a higher CPU.
4. Use the htop command that comes with the Linux system
   htop is an enhanced version of the top command. It provides a more friendly and intuitive interface and supports more operations. To check the CPU usage, enter the "htop" command in the terminal and press the Enter key. In the htop interface, you can visually understand the CPU usage of each process through color and percentage.

In addition to the above methods, there are many third-party tools that can help us check CPU usage, such as Process Explorer, GKrellM, etc. These tools usually provide more detailed data and charts that can help us better monitor and analyze CPU usage.

In short, checking CPU usage is a key step to identify system performance bottlenecks and optimize computer performance. By using Task Manager, WMIC, top command, htop command and other third-party tools, we can understand the CPU usage in real time and take appropriate measures as needed. I hope the above introduction can be helpful to everyone when checking CPU usage.
