A lot of users complain that PCR7 Binding is not supported in Windows 10/11. What causes the PCR7 Binding not supported error? How to fix it? Here, MiniTool will explore the answers.

What Is PCR7 Binding

PCR7 Binding is a technology that helps Windows users encrypt hard drives on their computers. It is different from Bitlocker. Bitlocker is used for Windows 11/10 Pro, Enterprise, or Education edition. Windows 11/10 Home users cannot use Bitlocker because Windows 11/10 Home does not support it. Instead, they can use the PCR7 Binding technology to encrypt their drives.

PCR7 Binding System Requirements

The PCR7 Binding technology requires some hardware specifications. The PCR7 Binding system requirements are as follows:

If your system has these hardware specifications, you can use the PCR7 Binding technology to encrypt your drives. If not, you will see a message in System Information that PCR7 Binding is not supported.

How to Check If PCR7 Binding Is Not Supported

You can check to see if your PC supports PCR7 binding in System Information. To do this, follow the steps below:

Step 1: Click Windows Search and type system information .

Step 2: Now, right-click on the System Information app and select Run as administrator . Click Yes on the UAC prompt.

Step 3: In the System Information application, make sure System Summary is selected in the left pane.

Step 4: If your device supports PCR7 Binding, you will see PCR7 Configuration Binding Possible . If not, you will see PCR7 Configuration Binding Not Possible .

Step 5: Then check whether you can enable Device Encryption. To do that, scroll down the System Information page and find Device Encryption Support . If your device doesn't support Device Encryption, you may see any of the following messages:

  • Reasons for failed automatic device encryption: TPM is not usable, PCR7 binding is not supported, Hardware Security Test Interface failed and device is not Modern Standby, Un-allowed DMA capable bus/device(s) detected, TPM is not usable.
  • Reasons for failed automatic device encryption: Hardware Security Test Interface failed and device is not Modern Standby.

How to Fix PCR7 Binding Is Not Supported

The reason why PCR7 Binding is not supported is that “the TPM and Secure Boot features are disabled; The BIOS boot mode is set to Legacy boot mode instead of UEFI mode; Modern Standby is not enabled”. After analyzing the causes, let's try the following 4 feasible ways to fix the “PCR7 binding is not supported” issue in order until you get the problem solved.

# 1. TPM Support

A TPM is a chip designed to provide hardware-based and security-related functions. It stores encryption keys to provide endpoint security for devices.

TPM is another requirement for Device Encryption on Windows devices. So, check if your device has a TPM chip installed.

Step 1: Press the Win + R key to open the Run dialog. Then type tpm.msc in it and press Enter .

Step 2: Then the Trusted Management Module Management will launch. If you see the message saying “Compatible TPM cannot be found”, there is no TPM on the computer. If you see the message saying “The TPM is ready to use”, you have it.

If you have Windows 11 installed, you probably meet most of the requirements for Device Encryption, including TPM 2.0 and UEFI firmware support. However, you may still need to enable the TPM in the BIOS setup utility .

# 2. Change the BIOS Mode to UEFI

As you know, there are 2 different BIOS modes – UEFI and Legacy . If you want to use Device Encryption, you need to set the UEFI as the BIOS mode.

You can open the System Information app to see if your BIOS mode is Legacy or UEFI. If your BIOS mode is Legacy, you should change it to UEFI. To change your BIOS mode from Legacy to UEFI, your disk partition style should be GPT instead of MBR.

To convert MBR to GPT or GPT to MBR without data loss, MiniTool Partition Wizard should be a good choice. Besides, the MiniTool software can help you convert NTFS to FAT32 without data loss , convert dynamic disk to basic disk , rebuild MBR , etc.
