Trusted Platform Module (TPM) 2.0 provides platform authentication support for Windows 8 and above UEFI systems, without the need for preboot authentication (PBA).
TPM is a platform that allows encryption to occur using keys within the TPM. TPM is also implemented in firmware for tablets.
Drive Encryption supports TPM 2.0 and TPM 1.2 on Windows 8 and above UEFI systems for the TPM autoboot and cold-boot protection features.
Use temporary autoboot feature during patching to reduce issues of preboot authentication. For details about TPM autoboot, see KB79784.
