Answer 1

If your Windows 11 system is prompting for a BitLocker recovery key after an update, and you do not have the key or password, there are a few steps you can take:

1. Check for Backup: First, check if you have backed up your BitLocker recovery key. It might be saved in your Microsoft account, printed out, or stored on a USB drive.
   • If you have access to your Microsoft account, you can visit https://myaccount.microsoft.com and check under the Devices tab for your BitLocker keys.
2. Recovery Options: If you cannot find the recovery key, you may need to use recovery options. You can try connecting the drive to another computer as a secondary drive to access your data, if possible.
3. Seek Help: If you are unable to recover the key or access your data, consider reaching out to a professional data recovery service or your IT department if applicable.
4. Backup Recovery Information: In the future, ensure that you back up your BitLocker recovery key to avoid similar issues. You can use a WMI script or the manage-bde.exe command to back up the recovery information.

Unfortunately, without the recovery key, accessing the encrypted drives may not be possible due to the security measures in place with BitLocker.

Answer 2

If your drive is encrypted with Bitlocker, the only place the Bitlocker Recovery key is automatically stored is on the associated Microsoft account on the link below, be sure to check any Microsoft account that may have been used on the PC and also any work or school account that may be linked to the PC.

Are you able to find the Bitlocker Recovery Key on any account that may have been used or linked to the laptop?

If not, do you have a safe backup of your files, or use a cloud service like OneDrive to sync your files online.

If you are unable to find the Bitlocker Recovery Key on any account that may have been used on that device, then I am sorry for the bad news, the only way to access that device is to create a bootable Windows 11 USB on another working PC and use that to clean install Windows and at the start of the installation, delete all partitions on the drive to remove the encryption, which will sadly result in loss of all data on the drive.
