What TPM version do I have?īefore you check the version, you need to know if TPM hardware is present. Tip: Not installing a TPM 2.0 module, or disabling the TPM option (or setting it to version 1.2 compatibility) is a method to prevent a Windows 11 upgade. If you want to know the exact details, Microsoft has more information on TPM. The differences in version 2.0 vs version 1.2 are that the new version offers better security features. Version 1.2, which is also present on a lot of older systems is not enough. To be specific, Windows 11 requires TPM version 2.0. Windows 10 already had functionality that used the TPM module, but with Windows 11, Microsoft has made the presence of TPM mandatory. And it is partly increased security, decryption of encrypted data is only possible in the system itself (containing the TPM module used for encryption). TPM is partly convenience, it is performing a task which otherwise would need to be performed by the CPU and software. Practically speaking, TPM is used for Windows Hello (face recognition, finder print recognition, iris login), BitLocker (drive encryption). In older boards, it is often possible to add a TPM module using a pin header.Īs mentioned the TPM module enable implementation of hardware-level security, which typically used for encryption of data. In the Windows device details the manufacturer can also show Intel or AMD. Manufacturers of TPM chips include Infineon, STMicroelectronics and Nuvoton. In some older systems a TPM chip can be added when not present. Most modern computers (required since 2016) will have a TPM chip on board. It generates encryption keys, which are not accessible from outside of the computer hardware. The TPM chip is used to provide a hardware-level security to Windows. TPM is implemented using a hardware chip on the motherboard of a computer. TPM is short for Trusted Platform Module.
