Fedora and Arch Linux, two popular Linux distributions, are now officially available for the Windows Subsystem for Linux (WSL). In the past, installing Fedora or Arch on WSL involved extra effort. Users needed to manually download and import tarballs or rely on unofficial Microsoft Store versions, many of which required payment. The introduction of WSL 2.4.4 marked a shift by adding native support for tar-based distributions, which package their OS files in a tar archive. This update allows distro developers like Fedora and Arch to offer official, free WSL versions.
