When encrypting Windows boot partition (the partition where the Windows directory is located, usually C:) with BitLocker, 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 you lose the BitLocker Startup Key one day, you cannot retrieve the BitLocker Startup Key by default, because Microsoft has not yet implemented this feature in Windows.
Fortunately, Hasleo has already implemented the feature of export BitLocker Startup Key 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.
