The quickest way to free up your CPU is by terminating the processes that are using the most power.

1. Press Ctrl + Shift + Esc on your keyboard to open the Task Manager.
2. Click on the CPU column header to sort the processes by their usage.
3. Look for any non-essential app using more than 20% of your CPU.

Step 2: Disable Unnecessary Startup Programs

Many apps automatically launch when you turn on your PC, running in the background and draining your CPU power all day.

1. Open the Task Manager again.
2. Click on the Startup apps icon on the left menu (the stopwatch icon).
3. Review the list of apps. If you see apps like Spotify, Microsoft Teams, or Discord enabled, right-click them and select Disable.
   Note: This will not delete the apps; it just stops them from opening automatically.

Step 3: Run SFC and DISM Scans

If a corrupted Windows system file is causing the high CPU usage, Windows has built-in tools to scan and repair itself automatically.

1. Click on the Windows Search bar and type CMD.
2. Right-click on Command Prompt and choose Run as administrator.
3. Type the following command and press Enter:
   sfc /scannow
4. Wait for the scan to finish. After that, type this command and press Enter:
   DISM /Online /Cleanup-Image /RestoreHealth
5. Restart your computer once both scans are complete.

Step 4: Change Your Power Plan Settings

Sometimes, the Windows power plan pushes the minimum processor state too high, forcing your CPU to work at maximum capacity unnecessarily.

1. Press Windows Key + R, type control, and press Enter to open the Control Panel.
2. Go to Hardware and Sound > Power Options.
3. Click on Change plan settings next to your active power plan, then click Change advanced power settings.
4. Expand Processor power management and then Minimum processor state.
5. Change both "On battery" and "Plugged in" settings to 5%. Click Apply and OK.

Step 5: Update Your Windows and Graphics Drivers

An outdated graphics driver can cause major compatibility conflicts with Windows 11, leading to sudden CPU spikes.

1. Go to Settings > Windows Update and click Check for updates. Install any pending updates.
2. Open your graphics software (Nvidia GeForce Experience, AMD Software, or Intel Graphics Command Center) and check for the latest driver updates.

Conclusion

By following these 5 steps, you should see an immediate drop in your Windows 11 CPU usage, resulting in a cooler, quieter, and much faster PC. Make sure to keep your system updated and regularly clean up your startup apps to maintain this peak performance.
