How to Enable or Disable the “Clear TPM” Button in Windows 11 Security App

What is TPM?

TPM stands for Trusted Platform Module. It’s a small chip inside your computer that keeps your information safe. It stores things like passwords and encryption keys. Think of it as a tiny security guard for your PC.

What Does the “Clear TPM” Button Do?

The “Clear TPM” button resets this security chip back to how it was when new. When you press it, your PC will restart. It will erase some security information. This includes your PIN and face or fingerprint login (Windows Hello). Only use this button if you really need to reset your TPM.
