This guide will help you understand what the Trusted Platform Module (TPM) is and show you simple ways to clear and reset it on your Windows 11 PC.

What is TPM?

TPM is a tiny chip inside your computer that helps keep your system safe. It stores special security keys that protect your information and make your device more secure.

If your computer has problems with TPM, clearing and resetting it can often fix the issue.

Important: Before you start, make sure to back up your important files. Clearing TPM can remove some security settings, like your PIN, so being safe is a good idea!
