A Trusted Cryptography Module (TCM) is a hardware device used to enhance the security of computing systems. These modules are part of a class of security solutions known as hardware security modules (HSMs) or trusted platform modules (TPMs). They provide secure cryptographic key storage, digital signature generation, and other cryptographic services essential for maintaining system integrity and security, especially in environments where data protection is a priority.

For Windows systems, the Trusted Cryptography Module typically refers to a TPM (Trusted Platform Module), which is a specialized chip embedded on the motherboard that provides hardware-based security functions. It is often used for features like BitLocker encryption, Windows Hello, secure boot, and credential protection.

If you're trying to install a driver for a Trusted Cryptography Module on Windows, the driver is usually related to the TPM module or another cryptographic hardware device. Below, I will explain how to check if you have a TPM chip, and how to install or update the driver.
