How to Clear and Reset TPM in Windows 11

What is TPM?

The Trusted Platform Module (TPM) is a dedicated security chip soldered onto your computer’s motherboard. It safeguards sensitive data like encryption keys to protect your system from external threats.

Resetting this module frequently resolves startup failures, such as error code 0x8007007f. Problems often arise when Windows 11 cannot properly access or utilize these built-in security features.

How to Reset TPM Using Windows Security App

The Windows Security app provides a graphical interface for managing hardware security:

Open the Windows Security app:

1. Click the Start menu ⊞ (the Windows icon in the bottom-left corner).
2. Type Windows Security in the search 🔍 box.
3. Click on the Windows Security app from the results.
4. In the app, go to Device security on the left menu or click its icon on the main page.

Open the Start menu ⊞, type Windows Security, and select the app from the search 🔍 results.

5. Click on Security processor details under the Security processor section.

Navigate to Device security in the left sidebar, and click Security processor details.

6. Next, click on Security processor troubleshooting.

Select Security processor troubleshooting to access the reset options.

7. Under the Clear TPM section, choose a reason why you want to clear TPM.
8. Click the Clear TPM button.

Choose the option to clear the security processor.

Your PC will restart, and the module will revert to factory defaults.

How to Reset TPM Using PowerShell

PowerShell offers a quicker route for administrative maintenance:

Open PowerShell:

1. Click Start, type PowerShell, right-click on it, and choose Run as administrator. ⚠️ Requires admin privileges
2. Type this command and press Enter:

Clear-TPM

Run the following command and hit Enter: Clear-Tpm. Your PC will restart and wipe the module automatically.

How to Reset TPM Using TPM Management Console

The TPM Management Console (tpm.msc), a legacy snap-in utility built into the operating system, handles advanced hardware administration.

1. Click the Start menu and type tpm.msc or Trusted Platform Module (TPM) Management, then open it. ⚠️ Requires admin privileges
2. In the top right corner of the window, click Clear TPM.

Press the Windows Key + R, type tpm.msc, and press Enter to launch the console.

The system might prompt you via a physical notification key on the keyboard to confirm the reset during the reboot sequence.

Hardware initialization completes automatically after the reboot finishes.

Common TPM Problem Messages

Specific error codes often point directly to malfunctioning cryptographic processors:

• A firmware update is needed for your TPM.
• TPM is disabled and needs your attention.
• TPM storage is not available. Please clear your TPM.
