In this guide, we will walk you through the most common causes of the 0xc00d7816 error, explain the steps to troubleshoot it, and provide preventive measures to ensure smooth performance in the future.

What is the 0xc00d7816 Error?

Before diving into the solutions, it’s essential to understand what the 0xc00d7816 error code means. This error is primarily related to the TPM on your device, a hardware-based security feature used for securing sensitive information and enabling features like Windows Hello and BitLocker encryption. When there is an issue with the TPM, Windows may show this error, causing authentication problems or preventing secure features from working.

Common Causes of the 0xc00d7816 Error

Several factors can lead to the appearance of the 0xc00d7816 error. These may include:

  1. Corruption of TPM Data: Over time, the data stored in the TPM can become corrupted, leading to security feature malfunctions.
  2. Misconfigured TPM Settings: Incorrect BIOS/UEFI settings can disable or misconfigure the TPM, leading to errors like 0xc00d7816.
  3. Windows Update Conflicts: Some updates to Windows can interfere with TPM functionality, causing errors.
  4. Hardware Changes: Replacing or upgrading certain hardware components, such as the motherboard or storage drives, may disrupt the TPM’s functioning.

Understanding these causes will help you identify the right solution for the issue.


How to Fix the 0xc00d7816 Error: Step-by-Step Guide

There are several ways to resolve the 0xc00d7816 error, and we will guide you through the most effective solutions. Here is a step-by-step troubleshooting process to fix the issue.

1. Clear the TPM Data

The first step in resolving the error is to clear the TPM. This process resets the TPM to its factory state, removing any corrupted data that may have caused the issue.

  • Press Win + R to open the Run dialog.
  • Type tpm.msc and press Enter.
  • In the TPM Management window, locate the option to “Clear TPM” under the Actions section.
  • Follow the on-screen prompts to clear the TPM and restart your computer.

Clearing the TPM may resolve any corruption in the stored data and allow secure features to work correctly again.

2. Update Your BIOS/UEFI Firmware

Another critical step in resolving TPM-related errors is ensuring that your BIOS/UEFI firmware is up to date. An outdated firmware version can cause issues with TPM functionality.

  • Go to your computer manufacturer’s website and search for the latest BIOS/UEFI update for your specific model.
  • Follow the provided instructions to update the firmware.
  • After updating, restart your device and check if the issue is resolved.

Updating the firmware can fix known bugs and improve compatibility with TPM, thus eliminating the 0xc00d7816 error.

3. Check and Modify BIOS/UEFI TPM Settings

In some cases, the TPM settings in the BIOS/UEFI may be misconfigured. To check and modify these settings:

  • Restart your computer and press the designated key (often F2, F10, or Delete) to enter the BIOS/UEFI setup.
  • Navigate to the Security or Advanced tab, depending on your motherboard.
  • Look for TPM settings and make sure TPM is enabled.
  • If available, select the option to clear TPM and save the changes.

By ensuring that TPM is enabled and properly configured, you can avoid issues that trigger the 0xc00d7816 error.

4. Remove and Re-Add Your Device from Azure Active Directory

If your device is enrolled in Azure Active Directory (AAD), it could be worth removing and re-adding the device. This process may help resolve conflicts caused by authentication issues.

  • Go to Settings > Accounts > Access work or school.
  • Select your Azure AD account and click Remove.
  • Then, add the account back by selecting Add a work or school account and following the on-screen prompts.

Re-registering your device with Azure AD can fix problems related to the TPM and authentication errors.

5. Perform a System Update

Make sure that your Windows operating system is up to date, as some updates contain fixes for TPM-related issues.

  • Go to Settings > Update & Security > Windows Update.
  • Click on Check for updates and install any available updates.
  • Restart your computer after installing updates.

Updating Windows ensures that your system has the latest patches and bug fixes, which may address the 0xc00d7816 error.

6. Reset Windows

As a last resort, you can reset Windows to its default settings. This process will reinstall the operating system and fix any underlying issues with the TPM and system configuration.

  • Go to Settings > Update & Security > Recovery.
  • Click on Reset this PC and choose whether to keep your files or perform a full reset.

Performing a reset will wipe out potential issues with system settings, but it should only be used if other solutions haven’t worked.


Preventive Measures to Avoid the 0xc00d7816 Error

Once you’ve fixed the error, it’s essential to take steps to prevent it from happening again. Here are a few preventive measures:

Regularly Update Your System

Ensure that both your Windows operating system and BIOS/UEFI firmware are regularly updated. Keeping your system up to date will help prevent compatibility issues and address known vulnerabilities that could affect TPM functionality.

Back Up Important Data

Since troubleshooting the 0xc00d7816 error may involve resetting your device or clearing the TPM, it’s essential to back up your important data before proceeding with any of the solutions.

Monitor TPM Health

Occasionally check the health of your TPM using the tpm.msc tool to ensure it is functioning properly. Keeping an eye on this will help you address issues before they become critical.
