About this tag
The wsl tag on WindowsForum.com covers Windows Subsystem for Linux topics, including WSL2 kernel updates, deployment best practices, and developer configurations. Recent discussions highlight kernel fixes for timekeeping and security vulnerabilities, the importance of controlled WSL 2.7.x rollouts, and using Windows Developer Configurations to provision WSL environments. The tag also touches on Linux terminal tools for Git, tmux, and Python, as well as related Azure BlobFuse migration guidance. For IT administrators and developers, the tag offers practical advice on managing WSL updates, validating kernel patches, and integrating WSL into modern Windows development workflows.

    WSL 3.0.3 pre-release bumps the kernel to 6.18 and polishes wslc

    Microsoft has published WSL 3.0.3 on GitHub, the third update on the 3.0 line since WSL Containers went generally available at the end of September. It is a pre-release, not a stable rollout, and it reads like one: a kernel bump, a handful of genuinely useful wslc improvements, and a pile of...

    WSL 3.0.2 Pre-Release Adds vNUMA for Large VMs and Experimental Sparse VHDs

    Microsoft has published WSL 3.0.2, a quick follow-up to last week's WSL 3.0.1. It carries two changes that matter to two very different groups. Owners of very large multi-socket machines get automatic virtual NUMA (vNUMA) for large WSL virtual machines. Developers who keep running out of disk...

    Do More Developers Use Windows? Survey Context, macOS Polls and WSL Containers

    Microsoft Distinguished Engineer David Fowler has stepped into a small X brawl over who actually uses Windows. His answer is "more developers than anything else." That is probably true. It also doesn't settle the argument it was meant to settle. What happened Windows Latest reports that an X...

    OpenCode on Windows: WSL Setup, AI Provider Freedom, Azure OpenAI and Subscription Limits

    Plenty of developers have tried a new AI coding agent, liked it for a week, and gone back to what they used before. XDA's Parth Shah says OpenCode is the exception for him. After testing what he calls "dozens" of Claude Code alternatives, the open-source agent is the one he keeps using. This is...

    Windows Developer Poll: 12.8% Does Not Prove an Exodus

    Windows accounted for 12.8% of responses in an informal developer poll reported by Windows Latest on September 22, 2026, but the result does not establish that developers broadly are abandoning Microsoft’s operating system—or that its Windows 11 developer-tooling changes have failed. The poll is...

    WSL and Linux Shell Errors That Delete Data or Block SSH

    How-To Geek’s September 18 guide to “innocent-looking” Linux commands gets the central warning right: a missing character or an unexamined paste can erase a home directory, silently truncate a configuration file, cut off remote administration, or exhaust a machine’s process table. But these four...

    Microsoft has issued KB5129242, an out-of-band cumulative update for Windows 11 version 23H2, bringing the OS to build 22631.7584. The update matters less as a routine build increment than as a targeted response to three distinct post-update problems: Remote Desktop Services instability, broken...

    Starling on WSL: What Windows Users Should Know

    Starling is a provocative Linux desktop experiment with direct relevance to Windows users because its documented 0.4.0 WSL mode can present a complete Linux desktop through an RDP connection to localhost.

    WSL 2.9.9 Fixes WSLC Stalls; 2.7.12 Remains Stable

    Microsoft released WSL 2.9.9 as a pre-release on August 25, with changes that matter far more to WSL Containers pilots and managed networking deployments than to an ordinary Ubuntu-on-Windows workstation. The GitHub release record identifies the build as pre-release, while WSL 2.7.12, published...

    CVE-2026-64117 is a newly published Linux kernel vulnerability in the Wi-Fi stack that deserves attention not because it affects every wireless device, but because it sits in a privileged and security-sensitive part of the networking path. The flaw, resolved upstream before public CVE...
