This article describes Trusted Boot, a security measure built into Windows 11 to prevent malware and corrupted components from loading when a Windows 11 device is starting. Trusted Boot picks up where Secure Boot leaves off, helping to ensure your Windows 11 system boots up safely and securely.

Trusted Boot takes over where Secure Boot leaves off. The Windows bootloader verifies the digital signature of the Windows kernel before loading it. The Windows kernel, in turn, verifies every other component of the Windows startup process, including boot drivers, startup files, and your antimalware product’s early-launch antimalware (ELAM) driver. If any of these files were tampered, the bootloader detects the problem and refuses to load the corrupted component. Tampering or malware attacks on the Windows boot sequence are blocked by the signature-enforcement handshakes between the UEFI, bootloader, kernel, and application environments.
Often, Windows can automatically repair the corrupted component, restoring the integrity of Windows and allowing the Windows 11 device to start normally.
