In this guide, we’ll show you how to turn on a special security feature called Firmware Protection on your Windows 11 PC. This helps keep your computer safe from tricky malware programs right from the moment it starts up.

What Is Firmware Protection?

Your computer has a part called firmware that helps it start up and run properly. Sometimes bad software tries to sneak in here, which is hard for regular antivirus programs to catch.

Firmware Protection works like a security guard at your PC’s startup, checking everything is safe before Windows even loads. This extra layer of protection helps:

• Stop malware attacks that try to hide deep inside your PC.
• Make sure only trusted software runs when your PC turns on.
• Keep your PC’s firmware safe from being changed without permission.
• Give extra security to special devices called Secured-core PCs.

Note: Firmware protection is especially important if you store sensitive information or want strong security for your PC.

How to Turn On Firmware Protection in Windows 11

If your computer supports it, here’s how you can enable this security feature using the Windows built-in security app.

1. Open the Windows Security app. You can do this by clicking the Start button, then selecting Settings > Privacy & Security > Windows Security, and then click Open Windows Security.
2. In the Windows Security window, click on Device security.
3. Look for the section called Core isolation and click on Core isolation details.
4. Find the switch for Firmware protection and toggle it On.

If the Firmware Protection option is grayed out and you can’t change it, you may need to adjust a setting in the Windows Registry. (Don’t worry, we’ll explain that below.)

After turning it on, restart your computer to make sure the changes take effect.
