High CPU usage and high temperatures in Windows 11 usually mean some apps or background processes are consuming a lot of resources. To improve performance and reduce heat, use these steps:
- Identify and close heavy CPU apps
- Press Ctrl + Shift + Esc to open Task Manager.
- Select More details if needed.
- On the Processes tab, select the CPU column to sort by usage.
- Right-click apps using a lot of CPU that are not needed and select End task.
- Disable unnecessary startup apps
- In Task Manager, select Startup apps from the left menu.
- Right-click apps that do not need to start with Windows and select Disable.
Reducing startup apps lowers background CPU usage and can reduce heat.
- Turn off background activity for apps
- Select Start > Settings > Apps > Installed apps.
- For apps that do not need to run in the background, select More options (… ) > Advanced options.
- Under Background app permissions, set Let this app run in the background to Never.
- Free up disk space
Low disk space can slow the system and increase load on the CPU.
- Run Storage Sense:
- Select Start > Settings > System > Storage.
- Select Storage Sense.
- Select Run Storage sense now.
- Clear temporary files manually:
- Go to Start > Settings > System > Storage.
- Select Temporary files, choose what to remove, then select Remove files.
- Use Disk Cleanup:
- Select Start, type Disk Cleanup, and open it.
- Select the drive to clean and follow the prompts.
- Adjust visual effects for better performance
- Select Start, type Adjust the appearance and performance of Windows, and open it.
- On the Visual Effects tab, select Adjust for best performance.
This reduces graphics effects that consume CPU and GPU.
- Check power mode
If the device is always hot and on high performance, consider balancing performance and heat:
- Select Start > Settings > System > Power & sleep.
- Under Related settings, select Additional power settings.
- Choose a plan that is not always at maximum performance if heat is a concern.
- Keep drivers and firmware updated (especially on Surface devices)
- Open the Surface app if using a Surface device.
- Expand Help & support to check update status.
- If updates are available, select Check for updates to open Windows Update and install them.
Updated drivers and firmware can improve cooling and performance behavior.
- Monitor overall resource usage
- Press Ctrl + Shift + Esc to open Task Manager.
- Use the Performance tab to watch CPU, memory, and disk usage.
- If usage is constantly high even with few apps open, systematically close or uninstall apps that are not needed:
- Select Start > Settings > Apps > Installed apps.
- Uninstall apps that are not used.
If a specific app always causes high CPU and does not work correctly, consider reinstalling that app or using an alternative. If the problem persists system-wide after these steps, a repair install of Windows or contacting device support may be needed.
