The Raspberry Pi series has evolved into versatile systems, but running Windows has been challenging for enthusiasts. A recent project explored running Windows 11 on the Raspberry Pi 5 using Runtipi, a platform for deploying containers. This method allows Windows 11 to run in a container using KVM technology. The installation process took about 38-43 minutes, resulting in a Windows 11 desktop with limited performance, including a capped display resolution of 800x600. Geekbench 6 tests showed single-core performance similar to Raspberry Pi OS, but multi-core performance was lower. Running PC games resulted in long load times and resolution issues, making the experience unsatisfactory. The containerized approach simplifies the installation process compared to traditional methods, making it a viable option for running lightweight applications on the Raspberry Pi.

The author transformed a mini PC into a basic Network Attached Storage (NAS) solution using a standard Windows installation. While Windows can work for simple setups, it is generally inefficient for NAS due to its resource usage, lack of native ZFS support, forced updates, complicated Docker and VM management, and clunky remote access. Windows runs unnecessary background services that consume RAM and storage, while dedicated NAS software optimizes performance. Windows does not support ZFS natively, which is beneficial for data integrity and features like compression and encryption. Windows updates can disrupt services due to their unpredictable nature, unlike dedicated NAS systems that allow for scheduled updates. Managing Docker containers or virtual machines is more complex on Windows compared to Linux, which is better suited for these tasks. Remote access on Windows requires cumbersome setups, while Linux offers easier SSH access and web interfaces for management.

An Arch Linux image for the Windows Subsystem for Linux (WSL) is being developed by Arch Linux package maintainer Robin Candau. Microsoft has shown interest in supporting this project, which will feature a monthly update cycle similar to Fedora 42. Key aspects include: - A dedicated repository for Arch Linux WSL will be created on Arch Linux's GitLab. - Monthly images for Arch Linux WSL will be automatically built and published using Docker/container images with systemd support. - The image will not be available through the Microsoft Store but can be downloaded as tarballs for installation on Windows. - Technical support will be provided on a best-effort basis for WSL2, with no support for WSL1. - Arch Linux staff are not obligated to provide assistance. Previous attempts to run Arch Linux on WSL exist, but this official initiative adds legitimacy. Robin is ready to work with the Arch Linux DevOps team to start the setup unless significant objections arise. An experimental repository is available on GitLab for further exploration.
