How to Enable All Cores in Windows 10: Boost Your PC’s Performance

posted on June 20, 2025

Enabling all cores in Windows 10 can help your computer perform better by making full use of your processor’s power. To enable all cores, you’ll need to access the System Configuration tool and adjust the Boot settings. This involves navigating through a few menus but is a relatively simple process. Once completed, your computer should be able to handle more demanding tasks efficiently.

How to Enable All Cores in Windows 10

By enabling all cores in Windows 10, your computer can take advantage of all the processing power available, which can speed up performance for certain tasks. Let’s walk through the steps to get this done.

Step 1: Open the System Configuration Tool

To start, press the Windows key and type "msconfig" in the search bar, then hit enter.

The System Configuration tool is a handy feature in Windows that lets you control how your computer starts up and runs. It’s like the command center for your PC’s boot settings.

Step 2: Navigate to the Boot Tab

In the System Configuration window, click on the "Boot" tab.

This tab is where you’ll find all the options related to how your computer starts up. It’s the go-to place for adjusting boot settings, including the number of processor cores.

Step 3: Open Advanced Options

Click the "Advanced options" button in the Boot tab.

The Advanced Options menu gives you more control over your system’s startup, including which and how many processor cores to use when booting.

Step 4: Adjust the Number of Processors

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

This step is crucial as it allows you to specify how many cores your processor can use, unlocking more of your computer’s potential.

Step 5: Save Your Settings and Restart

Click "OK" to close the Advanced Options, then "Apply" and "OK" in the System Configuration window, followed by a reboot of your system.

Saving these settings and restarting your computer is necessary for the changes to take effect. It’s like giving your PC a little nudge to wake it up fully.

After completing these steps, your computer will utilize all available processor cores, potentially improving performance for tasks that require more computing power, like gaming or video editing.

  • Monitor Performance: Use Task Manager to see if enabling all cores benefits your system’s performance.
  • Backup Data: It’s always a good idea to backup important data before making system changes.
  • Consult Professionals: If unsure, consider consulting a tech professional to avoid any missteps.
