    Hi,

    The BitLocker recovery key is usually stored in the Microsoft account that was used to set it up, whether it is a personal account or a work or school account.

    As this is a public forum for fellow users like you, we do not have access to individual Microsoft accounts. Try signing in to all the Microsoft accounts you remember to see if you can find the recovery key.

    Personal Microsoft account:

    https://account.microsoft.com/devices/recoverykey

    Work or school account:

    https://aka.ms/aadrecoverykey

    If you did not set up BitLocker on your computer yourself, it is most likely that it was enabled by default by the manufacturer or by the person who initially set up your computer.

    Unfortunately, only the person who set up BitLocker can access the recovery key for security reasons. Even Microsoft Support does not have access to it.

    If you cannot find the recovery key, I’m sorry, but there is no way to bypass BitLocker. In this situation, formatting the hard drive and performing a clean installation of the Windows OS will be necessary. Please note that this process will result in data loss.

    Find an empty USB drive with at least 8 GB of space and a working computer, then follow the steps below:

    1. Click this link: https://www.microsoft.com/software-download/windows11

    Under Download Windows 11 Disk Image (ISO), Click on "Download tool now."

    1. Run the tool, create a bootable USB drive or ISO file, and deselect the 'Use the recommended options for this PC' box to choose the correct language and edition.

    Once the process is done:

    1. Connect the installation media to your PC.
    2. Start your PC and press any key to continue. Click Next > Click Install Now.
    3. When the Windows Setup starts, follow the on-screen instructions.

    Note: If prompted for a product key, click 'I do not have a product key' and then click Next.

    Make sure you install the same edition of Windows 11 (Home or Pro) that you previously had installed to avoid activation issues.

    For a step-by-step guide with illustrations, click the link below and scroll down to the 'Steps to reinstall Windows with media' section, then expand the 'Clean install' option:

    A BitLocker recovery key is a 48-digit numerical password used to unlock the encrypted drive.

    To find which account has the key, use the recovery key ID shown on the BitLocker screen and check these locations:

    1. Note the first 8 digits of the recovery key ID on the recovery screen.
    2. Check the Microsoft account recovery key page from another device: https://aka.ms/myrecoverykey
      • Sign in with each Microsoft account that might have been used to set up the laptop.
      • Match the key ID shown on the website with the key ID on the laptop.
    3. If the laptop was ever signed in with a work or school account, check: https://aka.ms/aadrecoverykey
      • Sign in with the work or school account.
      • Go to Devices, expand the device, and select View BitLocker Keys.
    4. If the device is managed by an organization, the recovery key might also be available through the Intune Company Portal:
      • Sign in to the Company Portal website
      • Go to Devices
      • Select the locked PC
      • Select Get recovery key > Show recovery key
    5. Also check whether the key was saved elsewhere when BitLocker was turned on:
      • a printed copy
      • a USB flash drive containing the saved key

    Important facts:

    • Microsoft Support cannot retrieve, provide, or recreate a lost BitLocker recovery key.
    • If the device was set up or BitLocker was turned on by someone else, the key might be stored in that person’s Microsoft account.
    • If the recovery key cannot be found, the remaining option is to reset the device using Windows recovery options. This removes all files.
