Bitlocker key issue, don't know microsoft account linked with my laptop. Please help . Important data Phd work is in it. I don't want to lose it at any cost. Please help. I don't have Microsoft account linked with that laptop, i purchased the laptop 4 years back, don't know what account shopkeeper added in it. Any other way to get it like command prompt, restoring laptop without removing files in the laptop. I have very very important data, my 4 years of hard work phd thesis. Or can i recover the data by removing ssd from laptop and using it somewhere else ,i mean in other systems.

    The BitLocker recovery key is linked to the Microsoft account used on the system. You can try to access it here:
    https://account.microsoft.com/devices/recoverykey

    This article provides detailed information on how to find the key: https://support.microsoft.com/windows/find-your-bitlocker-recovery-key-6b71ad27-0b89-ea08-f143-056f5ab347d6

    Unfortunately, if the recovery key is not available, it won’t be possible to access the system because of BitLocker encryption. In this case, the only option is to format the hard drive and reinstall Windows.
