How to Clear TPM in Windows 11

The TPM (Trusted Platform Module) is a cryptographic processor aimed at improving your system's privacy and security. However, if you need to clear the TPM for whatever reason, this article will show you how to do that.


A TPM chip is a secure crypto-processor on your PC's motherboard that handles hardware-level encryption.

The TPM allows you to use biometrics to log in to Windows and encrypt data on your PC, and store part of the encryption key for BitLocker. In addition to encryption keys, it can store passwords and certificates.

Many apps and other PC features use the TPM. Email clients, such as Outlook and Thunderbird, use TPM to handle encrypted or key-signed messages. The Firefox and Chrome web browsers also use TPM for advanced functions, such as maintaining SSL certificates for websites.

By Clearing the TPM, you will lose all of the keys associated with the TPM and the data, such as the login PIN, smart card, and other data secured by those keys.

Before you clear the TPM, make sure to backup all data that is secured or encrypted by the TPM.

There are a few ways you can clear the TPM on your system. The guide below contains step-by-step instructions on how to do it.
