Microsoft denies WSL 3 exists, reveals Windows 11’s WSL Containers ship next week

Microsoft has clarified that there is no WSL 3 in development, as stated by Craig Loewen, the Product Manager for the Windows Subsystem for Linux (WSL). The confusion arose from articles discussing a new feature called WSL Containers, which will be launched soon. WSL allows users to run Linux environments on Windows without dual-booting, while WSL Containers enable the creation and management of Linux containers directly within Windows, eliminating the need for third-party tools like Docker Desktop. WSL 1, introduced in 2016, served as a translation layer for Linux system calls, and WSL 2, launched in 2019, included a full Linux kernel in a lightweight virtual machine. WSL Containers is an enhancement to WSL, allowing developers to build, run, and deploy containers directly from Windows using the wslc.exe command. This feature is part of Microsoft's strategy to make Windows a more accessible platform for running Linux workloads, helping to retain developers who might consider switching to other operating systems.

Making Windows a developer platform, again

Setting up a PC with the base Dev Config has been streamlined for developers, utilizing the Winget configuration service to install applications, execute updates, and apply developer settings on Windows. Users can access setup scripts by cloning a GitHub repository or downloading a zip archive, with clear instructions provided by Microsoft. The installation may require a reboot during the Windows Subsystem for Linux (WSL) installation, but the script resumes automatically afterward. The process installs applications such as PowerShell, Git, GitHub command-line interfaces, Windows App SDK, Visual Studio Code, and language support for Node.js, Python, and .NET. It also includes developer-friendly fonts and a theme engine for Windows Terminal, along with options for customizing File Explorer and the Windows Task Bar. After WSL installation, developers can use WSL Comfort scripts to install additional tools and personalize their Windows Terminal experience. This utility has two phases: the Windows component configures WSL and Ubuntu, while the Linux component fine-tunes the WSL environment, allowing for zsh and starship terminal display tools. It also integrates popular command-line interfaces and supports the Homebrew package installer, targeting existing Ubuntu instances without needing a new Linux distribution installation.

Why is Windows 11 so disliked by programmers – and can Microsoft do anything to change things?

Windows is experiencing a decline in favor among developers, with many preferring macOS and Linux for coding. Although nearly half of developers (49.5%) primarily work on Windows, this is often due to organizational mandates rather than personal preference. Developers interviewed did not select Windows as their preferred environment, citing concerns about Microsoft's developer experience, cumbersome tools, and security issues. The Windows Subsystem for Linux (WSL) allows developers to run Linux environments on Windows 11, addressing some compatibility issues. However, there is a consensus that Microsoft should enhance WSL and align Windows more closely with Linux to attract more developers. Critics also point to the intrusive nature of ads and upselling in Windows 11 as detracting from the developer experience.

Windows Platform Security and the Race to Secure AI Agents

Microsoft has introduced the Microsoft Execution Containers (MXC) SDK to establish Windows as a reliable operating system for autonomous agents, focusing on containment, identity, and manageability. The MXC framework serves as a policy-driven execution layer for agents on Windows and Windows Subsystem for Linux (WSL), allowing developers to set access permissions using JSON or TypeScript. It employs process and session isolation for agent containment and identity. Future enhancements will include micro-VM support for high-risk tasks and integration with Windows 365 for cloud PC workloads. IT teams can manage MXC policies through Entra ID and Intune, while Defender and Purview provide protection and observability. The MXC framework is built on Microsoft's security initiatives, including Secure Boot and passwordless sign-in, allowing agents to inherit a secure foundation. However, early commentary expresses caution regarding MXC's perception as a comprehensive security solution, noting issues with overly permissive policies and the lack of outbound network filtering. Other platforms, such as Linux, are also enhancing security for agents with kernel-level isolation and secure environments like NVIDIA's OpenShell runtime. Various projects are focusing on agent sandboxes within Kubernetes, employing technologies like gVisor and Kata Containers for isolation. Overall, no singular dominant platform security model for AI agents has emerged, with Windows' MXC still considered nascent compared to existing solutions in Linux and Kubernetes ecosystems.

A Brief History Of Unix Commands On Windows: CoreUtils (Again)

The interaction between Unix/Linux and Windows has historically been marked by significant differences in their architectures and philosophies. Unix uses a fork() function for process management, while Windows employs CreateProcess(), complicating the implementation of Unix-like tools on Windows. Early solutions to bridge this gap included the MKS Toolkit, which provided Unix-like commands for Windows, and UWIN from AT&T Bell Labs, which aimed to create a Unix interface layer on Windows. Cygwin offered a compatibility DLL to run Unix software on Windows, but required rebuilding from source. Microsoft's initiatives included POSIX, Interix, and later Services for UNIX. The introduction of the Windows Subsystem for Linux (WSL) allowed users to run a Linux userland directly on Windows, with WSL 2 incorporating a real Linux kernel. Recently, Microsoft released Coreutils for Windows, providing native builds of Unix-style tools to enhance cross-platform consistency.
