This button is located near the bottom of the Boot tab. It opens a new window where you can adjust the number of processors your system uses during boot-up.

Step 4: Enable All Processors

Check the box next to "Number of processors," then select the highest number available from the dropdown menu.

Selecting the highest number ensures all cores are being used. This will maximize your CPU’s performance capabilities.

Step 5: Apply Settings and Restart

Click "OK" to close the Advanced Options window, then click "Apply" and "OK" in the System Configuration window. Restart your computer to apply the changes.

Restarting allows Windows 11 to reconfigure its settings and start utilizing all the cores in your CPU effectively.

Once you complete these steps, your computer will start using all its CPU cores, leading to enhanced performance. You should notice faster boot times and smoother operation, especially during high-demand tasks like gaming or video editing.

Tips for Enabling All Cores in Windows 11

  • Backup First: Always make a backup of your important data before making system changes.
  • Check CPU Specs: Make sure your CPU actually has multiple cores. You can check this in the Task Manager under the Performance tab.
  • Update Drivers: Ensure all your drivers, especially for the CPU, are up to date to avoid compatibility issues.
  • Monitor Performance: Use performance monitoring tools to track any improvements or issues after enabling all cores.
  • Revert if Needed: If you encounter any problems, you can always go back to the System Configuration and deselect the "Number of processors" option.
