Summary

Hide ▲

Microsoft has rolled out hardware-accelerated BitLocker in Windows 11 to enhance performance and security. This update leverages system-on-a-chip (SoC) and CPU capabilities to offload cryptographic operations, reducing CPU usage and improving overall system performance. The new BitLocker utilizes hardware-protected keys, minimizing exposure to cyberattacks and enhancing security alongside Trusted Platform Module (TPM)–based key protection. This feature is available in Windows 11 24H2 and 25H2, with initial support for Intel vPro systems using Intel Core Ultra Series 3 processors.
