When you do get the notification ‘This device cannot use a Trusted Platform Module,’ it could be because your computer lacks a TPM chip or because of group policies. Users have reported receiving the above error message while attempting to encrypt a drive on Windows 10 using the built-in BitLocker. If you look attentively at the error message, you’ll notice the solution; unfortunately, not everyone has the skills to apply the workaround.
BitLocker is a key feature of Windows 10 that comes in useful when we need to encrypt particular hard disks to prevent unauthorized access. If you’re unfamiliar, the Trusted Platform Module, or TPM, is a chip found in most motherboards that are used to generate and store cryptographic keys. After reading this article, you will be able to get around the problem.

BitLocker
BitLocker is an important function in Windows. This program is useful if you wish to encrypt a drive to prevent others from accessing it and protect data. Starting with Windows Vista, it is only available in Windows Pro and Enterprise editions.
BitLocker’s encryption technique is AES in XTS or CBC (cipher block chaining) mode with a 128-bit or 256-bit key by default.
In a nutshell, BitLocker is an easy-to-use and sophisticated encryption tool that encrypts your whole hard drive and protects your system from illegal alterations.
3 Solutions of Fixing the Problem Trusted Platform Module Error
Solution 1: Allow Bitlocker to Function Without a TPM
As previously stated, the problem arises when your motherboard lacks a TPM chip. In this instance, you can disable BitLocker and use BitLocker without a TPM chip. To do so, you’ll need to change the group policy on your system. This is how you do it:
1. To launch the Run dialog box, press Windows Key + R.
2.Press Enter after typing ‘gpedit.msc’.
3. Go to the following directory once the Local Group Policy Editor has opened:
Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives
4. Double-click the policy titled “Require extra authentication at startup” to configure it.
5. The setting is set to Not Configured by default. It should now be set to Enabled.
6. After that, tick the box that says “Allow Bitlocker without a suitable TPM.”

7. Click OK after clicking Apply.
8. Restart your computer to see if the problem has been resolved.
Solution 2: Clear TPM
Clearing TPM is useful if you still want to use the TPM and make sure your system has the device as part of the hardware. Follow the steps below to get started:
Step 1: To open the Run window, press Win + R.
Step 2: Click OK after typing tpm.msc.

Step 3: Select Clear TPM from the Actions page and restart the system.
If TPM is turned off, go to the Actions tab and select Initialize TPM, then restart the computer. With the Turn on the TPM security hardware prompt, if TPM is never initialized, a wizard to set up TPM appears. Simply follow the wizard’s instructions and restart your computer.
Solution 3: Reset the Computer Domain
The problem is occasionally caused by the domain to which you are connected. If this is the case for you, you can try to fix the problem by leaving the domain and then rejoining it. To leave the domain, follow these steps:
1. To open Settings, press Windows Key + I.
2. Go to Accounts and then to the ‘Work and School Access’ tab.
3. Click Disconnect after selecting the domain to which you are connected.

4. Exit the domain by following the on-screen pop-ups.
5. Reboot your computer.
6. If you want to, you can join the domain again.
7. Check to see if the problem has been resolved.
