While most users prefer the official media creation tool, Rufus is a great option for installing Windows 11 on unsupported hardware or repairing the operating system and its quirks, such as:

  • automatic drive encryption without any warning (happens to insiders so far) during the installation process
  • hardware requirements or the need to use a Microsoft account during installation.
