// Helper: Simple MD5 or Hardware ID fetch (Stubbed for brevity - use a proper hash in prod) std::string GetMachineGUID() HKEY hKey; char buffer[128]; DWORD dwSize = sizeof(buffer);

The system queries the Windows Registry to retrieve the unique MachineGuid . This ensures the key cannot be used on a different computer.
