Success Case 1 (The Dead Motherboard): A user's laptop motherboard died. They moved the NVMe SSD to a new laptop. BitLocker locked it.

Success Case 2 (The Forgotten PIN): A business owner used a simple 4-digit PIN for BitLocker (not recommended). Sergei Strelec ran a brute-force attack on the PIN hash and found "2580" in 4 minutes.

Sergei Strelec is a popular WinPE-based bootable environment packed with recovery tools. It includes native BitLocker unlock capabilities—no need to decrypt the entire drive.
