If you receive this warning or critical alert, it means that your system is experiencing high CPU usage, which could lead to performance issues. - -### What does CPU utilization mean? - -`CPU utilization` is the percentage of time the CPU spends executing tasks, as opposed to being idle. A high CPU utilization means that the CPU is working on a large number of tasks and may not have enough processing power to handle additional tasks efficiently. This can result in slow response times and overall system performance issues. - -### Troubleshoot the alert - -1. Identify high CPU usage processes: - - Open Task Manager by pressing `Ctrl + Shift + Esc` on your keyboard, or right-click on the Taskbar and select "Task Manager." Click the "Processes" tab, and sort by the "CPU" column to identify the processes consuming the most CPU resources. - -2. Analyze process details: - - Right-click on the process with high CPU usage and select "Properties" or "Go to details" to learn more about the process, its location, and its purpose. - -3. Determine if the process is essential: - - Research the process in question to ensure that it is safe to terminate. Some processes are integral to the system, and terminating them may cause instability or crashes. - -4. Terminate or optimize the problematic process: - - If the process is not essential, you can right-click on it and select "End task" to stop it. If the process is necessary, consider optimizing its performance or updating the software responsible for the process. In some cases, restarting the system may help resolve temporary high CPU usage issues. - -5. Monitor CPU usage after taking action: - - Continue monitoring CPU usage to ensure that the issue has been resolved. If the problem persists, further investigation may be required, such as examining system logs or using performance analysis tools like Windows Performance Monitor. - -### Useful resources - -1.

If you receive this alert, it means your system's disk usage is high, and you might need to free up space. - -### Why is disk space utilization important? - -Disk space utilization is crucial for the stable and efficient operation of your system. As the disk fills up, system processes may slow down or fail due to insufficient storage space. Moreover, new applications and updates may require additional storage, which can cause issues if not enough disk space is available. - -### Troubleshoot the alert - -1. Check disk usage in detail - - To check the disk usage on your Windows system, you can use `Disk Management` tool by searching for it in the Start menu, or by right-clicking on Computer in the File Explorer and selecting "Manage." - -2. Analyze disk usage by folders and files - - Use a disk space analyzer tool like [TreeSize](https://www.jam-software.com/treesize_free) or [WinDirStat](https://windirstat.net/) to find the largest files and folders on your system. These tools will help you identify areas where you can free up space. - -3. Clean up unnecessary files - - - Empty the recycle bin on your Windows system. - - In the File Explorer, right-click on the system drive (usually C:), and select "Properties." Navigate to the "General" tab and click on "Disk Cleanup" to free up space by removing temporary files, system files and other items that can be safely deleted. - - Uninstall unused applications using the Programs and Features setting in the Control Panel. - - Move larger files such as media or documents to an external storage device or cloud storage service. - -4. Monitor disk usage - - Keep an eye on the disk usage to prevent it from surpassing the threshold again in the future.
