WSL is the best feature added to Windows in the last decade

Microsoft introduced the Windows Subsystem for Linux (WSL) in the Windows 10 Anniversary Update in August 2016, initially as a tool for developers. WSL debuted as a beta version with a native-kernel translation layer, allowing Windows to run unmodified Linux ELF binaries. Its early performance was limited, leading users to prefer Linux virtual machines for full compatibility. The launch of WSL2 in May 2020 replaced the translation layer with a lightweight, real Linux kernel running in a Hyper-V utility VM, providing near-native performance and comprehensive syscall coverage. WSL2 has since seen continuous improvements, including GPU-compute and CUDA support in 2021, full GUI support for X11 and Wayland applications in 2022, and systemd support in September 2022. WSL2 approaches the performance of bare-metal Linux while integrating seamlessly with Windows, allowing users to launch a Linux shell easily. It enables developers to access the C drive and interact between Windows and Linux environments without dual-booting. WSL2 enhances productivity for data science workflows, allowing the use of tools like PyTorch with CUDA. It also offers features for non-developers, such as creating aliases for launching Windows applications and running Linux GUI applications. WSL's integration into Windows represents a significant shift, providing opportunities for users across various domains to explore Linux functionalities.

I made my Windows Terminal exactly the way I want it, and it’s hard to go back to GUI apps

The author has been using Linux, specifically Ubuntu Server, for over a decade for cloud deployments, game server management, and media streaming. They primarily use a MacBook for daily tasks but also require Windows for gaming on a main PC, utilizing Windows Subsystem for Linux (WSL). The author has configured Windows Terminal to manage multiple command-line shells, including Windows PowerShell, Command Prompt, and WSL, all within a single application. Windows Terminal is pre-installed on Windows 11 version 22H2 or later and can be downloaded from the Microsoft Store for earlier versions. The author's Windows Terminal setup opens a WSL environment by default and includes options for Command Prompt, PowerShell, and Developer Command Prompts. They have customized their experience by removing trailing whitespace when pasting, organizing tab order, hiding the title bar, and using a Dark theme with the Monokai Remastered color scheme and JetBrains Mono font. The WSL configuration is set to access an Ubuntu terminal directly. Windows Terminal allows the author to connect to Proxmox hosts or virtual machines via SSH and supports multiple tabs for managing different systems. It features a "Quake" mode for quick command execution and the ability to create automated tools with keyboard shortcuts. The author plans to explore adding SSH profiles for easier server connections.

Microsoft finally makes Fedora an official Windows Subsystem for Linux (WSL) distribution

Fedora Linux has officially joined the Windows Subsystem for Linux (WSL), allowing users to run Fedora 42 within a Windows environment. Installation is straightforward with the command wsl --install FedoraLinux-42, and launching it requires wsl -d FedoraLinux-42, with no password needed by default. Users are automatically added to the wheel group for sudo access. Fedora 42 is streamlined, excluding unnecessary packages, and includes the DNF package manager, though Flatpak must be installed manually for graphical applications. The Fedora team is working on enhancing Flatpak support and introducing hardware-accelerated graphics for GUI applications in WSL. This inclusion of Fedora expands the options available to Windows users interested in the Linux ecosystem.

Windows 11’s WSL 2 now officially has support from Arch Linux

Arch Linux is now available on Microsoft's Windows Subsystem for Linux (WSL) for Windows 11 users. This release follows Fedora 42's addition to WSL. The collaboration between the Arch Linux team and Microsoft led to the creation of a dedicated GitLab repository for Arch Linux on WSL. Monthly updates will be provided, but this version is only compatible with WSL 2. Users can install Arch Linux on WSL using the command: wsl --install archlinux. After installation, it can be accessed via Windows Terminal or PowerShell. Performance is reported to be impressive, though it may vary based on user familiarity.

You can run Arch Linux in Windows now

Arch Linux has officially become available as a distribution for the Windows Subsystem for Linux (WSL). This release follows earlier reports from It's Foss News in February. WSL allows users to run a complete Linux environment on Windows, and the addition of Arch Linux introduces a rolling release model. The Arch Linux WSL image is maintained by Robin Candau and is built and released monthly through a GitLab CI schedule, with systemd support included. Users are advised to run pacman -Syu after their first launch to ensure they have the latest updates. To use Arch Linux on WSL, WSL 2 must be installed. The installation process involves running commands in PowerShell: PLACEHOLDER2f45746c1eb6702b for WSL 2, followed by PLACEHOLDERcebb97c90d3dc3e4 to add Arch Linux, and then PLACEHOLDERff7af59bfa5f1c11 to boot into it. Users should also update their system with PLACEHOLDERe23a8bb0ce81dc13. WSL 2 supports running Linux GUI desktops via Remote Desktop Protocol (RDP), but available images are primarily command-line based.

Windows 10 KB5055612 preview update fixes a GPU bug in WSL2

Microsoft has released the optional KB5055612 preview cumulative update for Windows 10 22H2, which addresses a GPU paravirtualization issue in the Windows Subsystem for Linux 2 (WSL2). This update is part of Microsoft's initiative for optional non-security preview updates, typically available at the end of each month, allowing administrators to test upcoming fixes and features. The update does not include security updates and can be installed manually through Windows Update or downloaded from the Microsoft Update Catalog. The key changes in the KB5055612 update include security improvements to internal Windows OS functionality, a fix for the case-sensitive GPU paravirtualization check in WSL2, and updates to the Windows Kernel Vulnerable Driver Blocklist to include drivers with known vulnerabilities exploited in BYOVD attacks. Microsoft has noted two known issues: one related to the Citrix Session Recording Agent (SRA) version 2411 causing update failures, with a suggested workaround, and another involving an Event 7023 error in Windows EventViewer regarding SgrmBroker.exe, which is currently non-functional and can be ignored. A fix for this bug is expected in future updates.
