Windows: Add registry setting to disable erasing encryption keys on Windows shutdown/reboot. This helps solve BSOD during shutdown/reboot on some machines.
Under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\veracrypt", create a REG_DWORD value named "VeraCryptEraseKeysShutdown" and set its value to 0.
