If you forgot your BitLocker recovery key, there are several ways to retrieve it.
If your computer is owned by a business and you've signed in using your work account, the recovery key may be in Azure Active Directory (AAD). Ask your IT department for assistance discovering it.
Another approach is to save the recovery key on a USB drive and insert it into the machine you're attempting to unlock. The file will then be recognized by Windows, and you may open it to get the key. This solution for aka.ms/myrecoverykey works well, but it is not infallible and is not guaranteed to operate if the hardware is updated.
The best approach to store the recovery key is in your Microsoft account. You may read it from any device with an internet connection if you save it in your account.
You may also use the command prompt to locate your recovery key. To launch the command prompt, hit Windows + S and then enter cmd into the search bar. Right-click cmd and choose Run as administrator.
Your BitLocker recovery key may also be found in the Windows system registry. Enter the recovery key identification and click the "OK" button to search for it. Then you'll see a list of recovery keys that are linked with the computer.
BitLocker is a built-in feature in Windows 10 that helps you encrypt your data. Once enabled, it requires you to enter a recovery key when you reboot the computer to unlock your drive. This is to prevent unauthorized users from accessing your encrypted data. When you first enable BitLocker, the wizard will ask you to save your aka.ms/myrecoverykey in a secure location.
