Sửa lỗi this device cannot use trusted platform module năm 2024

Encountering the message 'This device cannot use a Trusted Platform Module' while attempting to open BitLocker on a Windows 8 or Windows 10 PC is a common issue, often occurring on machines lacking a Trusted Platform Module (TPM) chip. Hence, this article will guide you through resolving the 'This device cannot use a Trusted Platform Module' error.

The full error notification reads: “This device cannot use a Trusted Platform Module. Your administrator must set the ‘Allow BitLocker without a compatible TPM’ option in the ‘Require additional authentication at startup policy for OS volumes.”

What exactly is a Trusted Platform Module (TPM)?

So, what exactly is the 'Trusted Platform Module' (TPM)? TPM is a physical chip installed on newer motherboards, storing security keys, such as drive encryption with BitLocker. If the motherboard lacks a TPM chip or if the BIOS or current drivers are not functioning properly, TPM won't operate.

The concept behind TPM is to provide a hardware link between your computer and its drive. Encryption keys stored on the TPM chip allow Windows to decrypt BitLocker when prompted. All you need to do is use your Windows password and the provided TPM password to unlock, and Windows will decrypt the data for use.

If any user were to steal your hard drive and plug it into their computer, they would need to attempt to decrypt the hard drive. Without keys stored on your motherboard, they cannot access your data.

Why might you receive the 'This device cannot use a Trusted Platform Module' error?

For some reason, Windows may be unable to access the TPM chip or it's not functioning properly. Before fixing the 'This device cannot use a Trusted Platform Module' error, you need to check the following basic issues:

- Verify the motherboard accurately, its model, and version to see if it has a TPM chip or not.

- Check the BIOS of the motherboard and drivers, and update if necessary.

- Not all motherboards come with TPM chips installed. Before proceeding with the troubleshooting process, ensure that your computer has a TPM chip.

- If your computer motherboard has a TPM chip, ensure that you're running the latest BIOS and driver version for the motherboard. Then try checking again.

Fixing the 'This device cannot use a Trusted Platform Module' error

If the error 'This device cannot use a Trusted Platform Module' persists, you can use the Group Policy Editor to resolve the issue.

Step 1: Enter gpedit.msc into the Cortana/Windows Search box to open the Local Group Policy Editor window.

Step 2: Navigate to the key:

Computer Configuration => Administrative Templates => Windows Components => BitLocker Drive Encryption => Operating System Drives.

Step 3: Look in the middle pane, locate the Require additional authentication at startup option.

Step 4: Right-click on it and select Edit.

Step 5: Choose Enabled at the top left of the left pane and check Allow BitLocker without a compatible TPM.

Step 6: Click OK and close the Group Policy Editor window.

Step 7: Select your hard drive, right-click on it, and choose Turn BitLocker on.

Now you'll see the BitLocker setup screen instead of the error notification. Your drive will be encrypted automatically, but instead of storing the key on a TPM chip, you'll need to use a USB drive. The process remains the same.

How do you set up Bitlocker?

If you want to set up BitLocker from scratch, here's how you do it. BitLocker is available for Windows 7 Ultimate, Windows 8, Windows 10 Professional, Enterprise, and Education. You can refer to Mytour's article on encrypting USB drives with BitLocker for detailed guidance.

If you're using one of these operating systems, you can use BitLocker to encrypt your hard drive.

Step 1: Open Control Panel and navigate to System and Security => BitLocker Drive Encryption.

Alternatively, right-click on the hard drive you want to encrypt and select Turn BitLocker on.

Step 2: Choose Turn BitLocker on to open the Setup wizard window.

Step 3: Select the unlock method. If your computer has TPM, choose TPM.

Otherwise, choose a password or USB flash drive. Passwords are easier to use but less secure. If you use a USB drive, you'll need to have the USB drive with you to connect to the encrypted drive.

Step 4: Back up the recovery key provided in the setup wizard window. Create multiple copies and store them in a secure location. You have the option to save the recovery key to your Microsoft account. However, this option seems somewhat less secure.

Step 5: Choose the option to encrypt only files rather than encrypting the entire drive. You can also choose to encrypt the drive, but this process takes a long time.

Step 6: The system will encrypt your drive and restart at least once. The process may be fast or slow depending on your computer's speed and the amount of data to be encrypted.

Step 7: Enter your password or insert your USB key to decrypt and access the data on the drive.

That's all you need to do to use BitLocker and fix the This device cannot use a Trusted Platform Module error on Windows computers. The process is quite simple and easy to follow. Just remember not to lose the key or USB drive you use to unlock the drive.

Windows encounters many unexpected errors that users cannot anticipate. The one mentioned here is just one of many other errors. However, the most annoying error for users is when the computer encounters network issues and cannot access the internet. Fixing network-related computer errors is also quite simple, and you can follow articles on Mytour to troubleshoot on your own.
