    I wish I could share good news, but the truth is no one can get you the bitlocker key, including Microsoft staff/support. https://support.microsoft.com/windows/find-your-bitlocker-recovery-key-6b71ad27-0b89-ea08-f143-056f5ab347d6 The link here says:"Important: Microsoft Support doesn't have the ability to retrieve, provide, or recreate a lost BitLocker recovery key."

    Is this where you looked? https://account.microsoft.com/devices/recoverykey

    If you set it up with school or work account, it is worth checking here as well https://aka.ms/aadrecoverykey sign in with your work/school email credential in that case.

    Any chance your laptop was purchased used, or already set up for you? Or was it gifted? Or have you set it up with a different account at first? The key is stored with the very Microsoft account used to set up the computer for the first time, even if you had got rid of that account and set it up with a different account. So, if your computer was set up by anyone at the store you bought it from, it would be that person's account.

    I assume you don't remember opting out of not saving it in Microsoft account, and saving it to a local file instead? That's another possibility.

    If you can't find it at all, there's really no way to go around it. Bitlocker means business. If it can be bypassed, then it means the encryption is not working. Your only option is to do a clean install of Windows. In that case, you do lose your files. I am very sorry.

    Use another phone or computer to open https://account.microsoft.com/devices/recoverykey, sign in with the Microsoft account used on the locked PC, and enter the 48-digit recovery key whose Key ID matches the one displayed on the BitLocker screen.

    A hardware change can cause BitLocker to request recovery even though the drive was working previously.^1^

    Retrieve and match the key

    1. On the BitLocker screen, write down the first eight digits of the recovery key ID.
    2. On another device, open: https://account.microsoft.com/devices/recoverykey
    3. Sign in using the same Microsoft account used to set up or sign in to this PC.
    4. If several keys appear, match the listed Key ID to the ID displayed on the locked computer.
    5. Enter the corresponding 48-digit recovery key on the BitLocker screen.

    The Key ID is only a label for identifying the correct key—it is not the number that unlocks the drive.^1^

    If the key is not in that account

    Check these supported locations:

    • Another person’s Microsoft account: If someone else originally configured the PC or enabled BitLocker, the key may be under that person’s account.
    • Work or school account: Visit https://aka.ms/aadrecoverykey, sign in, select Devices, expand the relevant device, and choose View BitLocker Keys. For a company-managed computer, contact IT and provide the displayed Key ID.
    • Printed copy: Check paperwork stored when the computer or BitLocker was configured.
    • USB drive: Connect any USB drive on which the key may have been saved. If it contains a text file, read it using another computer.^1^

    If no recovery key can be found

    Microsoft Support cannot retrieve, recreate, or bypass a missing BitLocker recovery key. The remaining option is to reset or reinstall Windows, which removes the files on the encrypted drive.^1^

    Do not format or reset the computer until every possible account, printed copy, and USB backup has been checked.
