Cause

NOTE: The version of security on your device (Intel PTT, AMD fTPM, or Microsoft TPM) depends on the BIOS installed on your computer. This article supports Windows 11, Windows 10, and Windows 8(8.1).

Resolution

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 running in memory.
  • Windows Hello: Secure user authentication without a 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.

Is Intel PTT, and AMD fTPM the same as TPM?

PTT or Platform Trust Technology is a firmware extension from Intel that supports Microsoft TPM requirements.

fTPM or Firmware TPM is a firmware technology from AMD that supports Microsoft TPM requirements.

Microsoft Windows works with both PTT and fTPM among other TPM implementations.
