When encrypting Windows boot partition, we can choose to start Windows with BitLocker password or startup key after the encryption is complete.
The BitLocker Startup Key file (.BEK) is a key file you would save on a USB drive to start Windows computer without having to enter the BitLocker recovery or password.
If we lose the BitLocker Startup Key one day, we cannot retrieve the BitLocker Startup Key by default, because Microsoft has not yet implemented this feature in Windows.
Fortunately, Hasleo has already implemented this feature in BitLocker Anywhere. With this tool, you can easily export BitLocker Startup Key from BitLocker encrypted drives as long as you have the correct BitLocker recovery Key, and this article will help you explain how it works.
Step 1. Download and install Hasleo BitLocker Anywhere.
Step 2. Launch Hasleo BitLocker Anywhere, right-click the drive letter you want to export BitLocker startup key, then click "Back up startup Key".
Step 3. Enter BitLocker Recovery Key, then click "Next".
Step 4. Select the drive where you want to back up the startup key to, then click "Save" to back up it.
With Hasleo BitLocker Anywhere, you can export BitLocker Startup Key from BitLocker Encrypted Drive not only on Windows 11/10/8/7 Home & Windows 7 Professional editions, but also on Windows 11/10/8/7 Enterprise & Windows Server editions.
