Monitoring CPU usage is crucial for maintaining the performance and stability of a Windows system. By tracking the CPU usage, system administrators and engineers can identify potential bottlenecks, resource-intensive processes, and optimize system performance. This article aims to provide a comprehensive guide on monitoring CPU usage specifically for the Windows environment.

Examples:

1. Using Task Manager:

   • Press Ctrl + Shift + Esc to open Task Manager.
   • Go to the "Processes" or "Details" tab.
   • Sort the processes by CPU usage to identify the most resource-intensive ones.

2. Using Performance Monitor:

   • Press Win + R and type "perfmon" to open Performance Monitor.
   • Expand "Monitoring Tools" and click on "Performance Monitor."
   • Click on the green plus icon to add a counter.
   • Select "Processor" from the drop-down menu and choose the desired counters (e.g., "% Processor Time").
   • Click "Add" and then "OK" to start monitoring the CPU usage.

3. Using PowerShell:

   • Open PowerShell as an administrator.
   • Run the command: Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select-Object -Property Name, PercentProcessorTime | Sort-Object -Property PercentProcessorTime -Descending
   • This command retrieves the CPU usage percentage for each processor core.
