WEBA TPM (Trusted Platform Module) is used to improve the security of your PC. It's used by services like BitLocker drive encryption, Windows Hello, and others, to securely create and store cryptographic keys, and to confirm that the operating system and firmware on your device are what they're supposed to be, and haven't been tampered with.
