Note: It is recommended not clear TPM via UEFI/BIOS. Below are some guides on Generation 1 and Generation 2 VM as regards to UEFI and BIOS: How to set up a Hyper-V Virtual Machine through PXE boot in Generation 2 VM" and " how to set up a VM via PXE boot on a Generation 1 VM".
UEFI was designed to overcome many limitations of the old BIOS. This ESP partition also contains the bootloader. efi file is stored on a special partition called EFI System Partition (ESP) on the hard disk. efi file, instead of storing it on the firmware. It does the same job as a BIOS ( Basic Input/Output System), but with one basic difference: it stores all data about initialization and startup in an. UEFI stands for Unified Extensible Firmware Interface. Kindly refer to these guides on how to determine if BitLocker is enabled: How to view BitLocker disk encryption status in Windows, how to enable Bitlocker Pre-Boot Authentication via the Group Policy, how to deploy Microsoft BitLocker Administration and Monitoring Tool, and how to enable or disable BitLocker Drive Encryption on Windows 10 and Virtual Machines. Some of the key advantages of using TPM technology are that you can generate, store, and limit the use of cryptographic keys, use TPM technology for platform device authentication by using the TPM’s unique RSA key, which is burned into itself, and help ensure platform integrity by taking and storing security measurements. The chip includes multiple physical security mechanisms to make it tamper-resistant, and malicious software is unable to tamper with the security functions of the TPM. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions.
