How to Make Windows 11 Safer with Firmware Protection
Firmware Protection in Windows 11 acts as a strong shield for your PC’s core software, stopping bad actors before they can cause harm.
This security feature checks that your device’s firmware, the basic software running hardware before Windows starts, stays true and hasn’t been tampered with.
Adding this protection is like giving your PC an extra bodyguard, especially useful against sneaky attacks that hit your computer as it boots up, even before your usual security programs can react.
Most computers made in the last several years already have the necessary pieces, like UEFI and TPM version 2.0, to use this protection.
Enable Firmware Protection by opening Windows Security, navigating to Device security, then Core isolation details, and toggling the Firmware protection switch to On. Restart your PC for the changes to take effect.
