How to Reset Windows Password on BitLocker Encrypted Drive

You are in luck if you have forgotten the administrator password for a Windows PC that utilizes BitLocker drive encryption. If BitLocker is activated on your hard disk, every one of your files will be encrypted. As a consequence of this, you are unable to access any system files, even if you launch the program using a Live CD, and you are also unable to reset the password for Windows that you have forgotten. Here is a guide to show you how to reset Windows password on BitLocker encrypted drive.

Use Windows bootable USB to reset Windows password on BitLocker encrypted drive

First, we need to create a bootable USB on a well-running Windows PC.

Part 1. Create Windows bootable USB via MediaCreationTool

Step 1. Download MediaCreationTool and run it as an administrator.

Step 2. Select ”Accept” in the license terms screen.

Step 3. Select “Create installation media for another PC”, and then select Next.

Step 4. Choose the language, edition, and architecture (64-bit or 32-bit) for Windows.

Step 5. Choose “USB flash drive” and click “Next”.

Step 6. Choose your prepared USB drive from the list, then “Next”.

Step 7. Once done, the tool will start to download the latest Windows 10 installation files to your device.

Part 2. Boot into Bootable USB to use CMD unlock BitLocker drive

Step 1. Plug the prepared USB into the PC and start it. Then enter BIOS and change the USB as the first boot order. Save the change and reboot the computer.

Step 2. When the Windows Setup window shows up, press “Shift”+ “f10” to summon CMD.

Step 3. Run the following command to check the BitLocker status of all drives and disk volumes on your computer.

You can see your system drive (Volume D in my case) is locked by BitLocker.

Step 3. Now you can use your BitLocker recovery key to unlock the encrypted system drive. Type the following command and press Enter key. Replace D with your operating system drive letter and replace "Your_BitLocker_Recovery_Key" with your BitLocker recovery key.

manage-bde -unlock D: -RecoveryPassword Your_BitLocker_Recover_Key

Alternatively, you may utilize your BitLocker password to access the encrypted system drive. Enter the command "manage-bde -unlock D: -Password" and press the Enter key. Please replace "D:" with the drive letter of your operating system. Just input your BitLocker password and press input to unlock the volume. You will be prompted to enter the password. The operating system volume will be successfully unlocked.

Step 4. Next, type manage-bde -off D: and press Enter key to decrypt the system drive.

When the "Percentage Encrypted" drops to 0.0%, that means the system drive is fully decrypted and BitLocker is turned off on the system drive.

Part 3. Reset Windows 10 local password

Now, we can use CMD to reset Windows password.

Step 1. In the command prompt window, run the following two command lines. Replace e with your operating system drive letter. That will replace the Ease of Access utility on Windows 10 sign-in screen with Command Prompt.

move d:\windows\system32\utilman.exe e:\windows\system32\utilman.exe.bak

copy d:\windows\system32\cmd.exe e:\windows\system32\utilman.exe

Step 2. Disconnect the Windows 10 installation media and restart your computer.

Step 3. After your computer restarts and arrives to the Windows 10 login screen, click the Ease of Access icon in the lower right corner of the login screen and a Command Prompt window will open.

Step 4. Run the following command to reset your local admin password. Replace "User_Name" with your local admin account's name and replace "New_Password" with the new password you want: net user User_Name New_Password

Step 5. Once the password is reset successfully, you can use the new password to sign in to Windows 10.

After you sign in, you can turn on BitLocker on your drive again if you want.
