So, without wasting a bit of time, proceed to the main solutions.


Fix 1 –  Check the Device Encryption Support

Before you do anything, check whether your system hardware supports the BitLocker Encryption at all. Follow these steps –

1. At first, press the Windows key+R keys together.

2. Then, write this in the box and hit Enter.

3. In the System Information page, highlight “Hardware Resources” on the left-hand pane.

4. Now, scroll all the way through the right-hand pane, and look for “Device Encryption Support“.


System Summary Device Encryption Min


Carefully notice what it is saying.

If it reads like “Meets Prerequisites“, then the BitLocker Encryption is fully supported on your system and jumps on to the main fixes to solve the problem.

But, if the condition states something like this –

Reason for failed automatic device Encryption: PCR7 binding is not supported, Hardware Security Test failed and the device is not Modern Standby.

In that case, the BitLocker Encryption is not supported by your system hardware.


Fix 2 – Edit the Registry Setting

You can manually edit the registry related to the BitLocker Encryption protocol using the Registry Editor.

1. Just click once on the Windows icon and type “regedit“.

2. Then, click “Registry Editor” which

Once you have created all the specified values, close the Registry Editor page.

Then, restart your computer. Restarting your computer saves these changes.


Fix 3 – Modify the Group Policy

If modifying the registry doesn’t fix the Bitlocker Encryption issue, you can use the group policy settings to manage the same.

NOTE – Group Policy is not available on Windows 11 Home edition. So, you can enact these only on Windows 11 Pro or Business edition devices.

1. Using the search box, perform a search for “group policy“.

2. Now, tap “Edit Group Policy” to open that.

5. Then, double-tap it so that you can edit it.

6. Make sure to switch the policy to the “Enabled” state.

7. Then, check this option on the Options pane –

8. Then, tap “Apply” and “OK” to save this modification.

Exit the Local Group Policy page. This policy change won’t take effect until you restart the system.

After restarting the computer, try to open the BitLocker Control Panel once more and test.


Fix 4 – Start the BDESVC

The BitLocker Drive Encryption service should be running while you are using any BitLocker features.
