Encountering high CPU usage in Windows 11 can significantly slow down your computer, affecting its performance and your productivity. A CPU running at 100% can be a sign of several issues, from software conflicts to malware infections. This article will guide you through the steps to troubleshoot and fix high CPU usage problems in Windows 11.
Understanding High CPU Usage
High CPU usage occurs when your processor is working at or near its maximum capacity. This can lead to slow performance, overheating, and in some cases, system crashes.
- Running too many programs simultaneously.
- Malware or virus infections.
- Outdated drivers or software.
- System settings and configurations.
Steps to Troubleshoot and Fix High CPU Usage
- Identify and Close High Usage Apps: Use Task Manager to identify apps with high CPU usage. Web browsers like Chrome are often culprits, especially with multiple tabs or streaming content.
- Limit Background Apps: Too many apps running in the background can hog CPU. Disable less useful apps entirely from running in the background by adjusting their settings in the ‘Apps & features’ section of Windows Settings.
- Restart Your Computer: A simple restart can temporarily fix high CPU usage, helping the system to return to normal operation before applying more permanent solutions.
- Update Windows: Running an outdated version of Windows can cause high CPU usage. Regularly check for and install updates via the Settings app.
- Restore Default Power Plan Settings : If you’ve altered power settings, restore them to default. Modified settings may affect performance and CPU usage.
- Disable Superfetch Service: Superfetch (Sysmain) helps apps load faster but can increase CPU usage. Temporarily disable it by changing its startup type to Disabled in the services menu.
- Disable Cortana: Microsoft’s digital assistant, though less intrusive in Windows 11, might still consume system resources. Disable it in the Apps section of Settings.
- Check for Updates During High Usage: If Windows is downloading or installing updates, CPU usage may temporarily increase. Check the Windows Update status and allow any updates to complete.
- Inspect Power Supply (Desktops): For desktops, ensure the power supply is adequate and the power cable is intact, as issues here can lead to high CPU usage.
- Scan for Malware and Adjust Antivirus Software : Malware can increase CPU usage. Use Windows Security to run a full system scan. Also, adjust settings in third-party antivirus software to prevent them from overusing CPU resources.
- Hardware Considerations: If your computer’s hardware is underpowered for your usage needs, consider upgrading components like RAM to better accommodate resource-intensive tasks.
Remember, these are general steps, and the effectiveness may vary based on individual system configurations and issues. If problems persist, consulting with a professional technician or Microsoft support may be advisable.
