Practically, the TPM is used for multiple features that increase the security of your device:


  • BitLocker Drive Encryption: Automatically encrypts the system drive to keep your data safe.
  • Data Execution Prevention: Prevents unauthorized applications like malware from executing in memory.
  • Windows Hello: Secure user authentication without password.
  • Secure Boot and Measured Boot: Block malicious drivers and rootkits from intercepting the boot process of the Operating system.


What is the difference between TPM 1.2 and TPM 2.0?


  • Version 2.0 provides higher security standards and better reliability.
