  2. The "Additional drivers" option allows us to inject drivers into the newly installed Windows, which is particularly important when we have to rely on hardware drivers to complete the Windows installation.
  3. The "Bypass internet connection requirement" option allows us to bypass the Internet connection requirement when installing Windows 11.
  4. The "Prevent automatic device encryption" option allows us to prevent automatic BitLocker device encryption when installing Windows 11.
