Resolve Common Issues with BitLocker on Windows

Today, we’ll analyze the situation and offer suitable solutions to address your challenges. We’ll cover BitLocker errors, TPM problems, recovery keys, solve error 0x8028400F, and more.

If you’re having trouble with encrypting or decrypting your hard drive, these solutions for common BitLocker problems will assist you in safeguarding your data.

Windows users are familiar with BitLocker, which is widely regarded as a reliable encryption system, despite occasional instances of uncooperative behavior. If you’re experiencing difficulties with BitLocker on Windows 10, you know exactly what we’re talking about. There’s no need to lose hope. Many BitLocker difficulties are common and easy to fix.

Can You Please Explain What BitLocker is?

If you value the security of your data, you’re likely familiar with BitLocker. However, if you’re new to this, let me give you a quick overview.

The Windows-specific BitLocker encryption solution is comprehensive. It protects your whole hard disk, not just data. BitLocker requires a password or smart card to access the encrypted disk. It is quite common for the original password to be misplaced. If this situation arises, the sole method to decrypt the Windows drive is by utilizing a BitLocker recovery key that was provided during the setup process.

Without the proper credentials, accessing a hard drive encrypted with BitLocker’s Advanced Encryption Standard (AES) algorithm is impossible.

BitLocker is widely used by corporations to secure data. BitLocker is bug-prone despite its strong security. Enabling BitLocker, finding the recovery key, and encrypting disks may be difficult.

Ways to Resolve BitLocker Problems on Windows 

There appears to be an issue with your BitLocker, and you’re uncertain about the cause? Many Windows 10 users have expressed frustration with various BitLocker issues, including password mishaps and encryption failures. However, in order to address your BitLocker issue, we need to first diagnose the problem. Then solve error 0x8028400F

Acknowledge and Identify the Issue at Hand – Solve Error 0x8028400F

The Windows operating system stores a record of BitLocker-related events in the Event Viewer application, specifically under Windows Logs > Application. Locating BitLocker event logs is a straightforward task, although comprehending their contents can be quite challenging. Text files need to be exported first, and this process involves coding.

Fortunately, error messages are less complex. The errors are coded, allowing for easy translation and research into their causes and solutions.

Presented below is a compilation of frequently encountered BitLocker error messages along with their respective explanations:

Error 0x8031003A: Oops! It seems like there’s an error with the key protector ID. Please make sure you’re using the correct and supported key protector.

Error 0x80310068: Sorry, but your PIN is too short. Please choose a longer PIN.

Error 0x803100CC: The PIN must contain both letters and numbers.

Error code 0x8028400F: Sorry, but we couldn’t locate the TPM (Trusted Platform Module) you’re looking for.

Sorry, but it is not possible to store BitLocker recovery information in Active Directory.

TPM not detected: Solve Error 0x8028400F

Sorry, but it seems that a compatible Trusted Platform Module (TPM) Security Device cannot be found on this computer.

Due to the fact

Windows uses TPM as a key protector by default. If you attempt to utilize a key protector that is not TPM, an error will occur. The error typically arises when your computer lacks compatible TPM hardware, yet you choose to proceed with BitLocker drive encryption regardless.


In order to solve error 0x8028400F issue, it is necessary to utilize a group policy setting that will supersede the default behavior. Here’s how you can accomplish that:

Please access the Group Policy editor: Both the local and domain group policies will be effective.

Go to the path: Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives.

Find the setting called “Require additional authentication at startup.”

Now, make sure to activate both this group policy setting and the checkbox that allows BitLocker to be used without a compatible TPM. This will require either a password or a startup key on a USB flash drive. Please refer to the screenshot for your convenience:

After completing this step, you have the option to utilize either a password or startup key as a key protector for the Windows volume.

If your computer is equipped with TPM hardware but you opt to utilize a key protector other than TPM, you may encounter one of the following error messages:

  • The use of a PIN at startup is not allowed due to group policy settings.
  • Sorry, but you’re not allowed to create a password due to the group policy settings.

Collect all the details about the problem

In order to accurately diagnose the issue, it is crucial to gather as much pertinent information as possible, not just from BitLocker. It’s important to have information about the version of Windows OS installed on your computer and the specific type of your BitLocker-encrypted hard drive.

Discovering crucial details about your hard drive is easy with these steps:

  • Press the Windows key and R.
  • Enter the command MSINFO32 and press Enter.
  • Navigate to Components and select either Storage, Drives (for standard information) or Disks (for more detailed information). Resolving problems with BitLocker

Ensure that the TPM is Enabled

TPM must be enabled for BitLocker to function. TPM, also known as Trusted Platform Module, is a hardware component that plays a crucial role in safeguarding the encryption keys on your Windows computer.

Not all computers are equipped with a TPM chip. Here’s a step-by-step guide to verify that:

  • Go ahead and open Start and search for Device Manager.
  • Access the application and navigate to the Security Devices section. If there is no TPM chip present, it is safe to conclude that your computer does not have one. How to Find TPM on Windows 10

TPM chips are commonly found in newer devices, but they may be disabled by default. Here’s a simple method to determine if your TPM chip is enabled:

  • Go ahead and open the Start menu and search for tpm.msc.
  • Please open the app for the Trusted Platform Module and navigate to the Status section. If your device has a TPM chip that is enabled, it will indicate that the TPM is ready for use. Verifying the TPM status on Windows 10

Make sure to check if there are any updates that need to be installed.

If you neglect to update your computer for an extended period of time, it becomes susceptible to bugs and malfunctions. It is important to check for updates before using the motherboard to fix BitLocker. If there are any updates, they can be quite beneficial in terms of saving you a significant amount of time and hassle.

  • Head over to Start and then click on Settings.
  • To check for updates, go to Windows Update and select the option to check for updates. Verifying Windows 10 updates
