Hello, First, please refer to this link to check if we can find the BitLocker recovery key: https://support.microsoft.com/en-us/windows/finding-your-bitlocker-recovery-key-in-windows-6b71ad27-0b89-ea08-f143-056f5ab347d6 In my experience, it's easy for computers to automatically enable BitLocker after a major hardware change. In this case, the only way to do this is to upgrade or reinstall the system. Best Regards, Hania Lian
