Fedora 42’s arrival as an official Windows Subsystem for Linux 2 (WSL2) distribution marks a significant milestone for both Fedora enthusiasts and the broader Windows open-source community. This integration brings some long-awaited legitimacy and convenience to users who have previously relied on unofficial Fedora spins or complicated setups to bridge the gap between the two operating system worlds. But with this new convenience come certain realities—chief among them, limitations in kernel freshness and the unique architecture that underpins WSL2. Let’s delve deeper into what this means for users, what strengths Fedora 42 brings to the Microsoft ecosystem, and the trade-offs that accompany this awaited partnership.
Fedora’s inclusion in the Microsoft Store as an official WSL2 option follows years of community requests and workaround-heavy installations. Previously, users seeking a Red Hat-flavored experience under Windows could turn to unofficial repackaged versions or alternative enterprise-focused offerings such as Oracle Linux and AlmaLinux. With Fedora 42, Microsoft and the Fedora Project are now offering a native, officially sanctioned image, removing friction and potentially lowering security risks associated with running unverified OS layers.
The news originated from Microsoft’s own Jeremy Cline, formerly of Red Hat and now the steward overseeing this project. Fedora’s prestigious lineage as a leading-edge, community-driven Linux distro means this announcement is especially relevant to developers and IT pros eager to use familiar tools and command structures within Windows environments.
The rollout of Fedora on WSL2 has been greeted positively across developer communities, with major coverage on sites like BetaNews and lively discussions on forums such as Slashdot and Reddit. This enthusiasm underscores the value to users of running popular and up-to-date Linux environments alongside Windows tools, without the overhead of maintaining separate physical or even virtual machines.
Yet, there’s a trade-off: the kernel version running under WSL2 is centrally managed and updated by Microsoft—not by the distribution maintainers. As of Fedora 42’s WSL2 launch, the kernel in use is 5.15.167-4-microsoft-standard-WSL2, a long-term support (LTS) release originally published in 2021. Despite Fedora’s reputation for living on the edge with cutting-edge packages, the system userland (the set of software and utilities shipped by Fedora) is now being layered atop an older, static kernel image. This approach delivers stability—ensuring robust and patched virtual environments—but it also means WSL2 users miss out on the latest kernel features.
The Fedora wiki and documentation are transparent about this compromise. WSL2 distributions operate as containers, sharing a uniform hypervisor-kernel platform rather than supplying their own kernels. For users whose workloads hinge on updated kernel modules, filesystems, or the bleeding-edge features Fedora usually provides, this could be a significant constraint. While the
But advanced Linux kernel hackers or those building kernel modules may be frustrated by their inability to control update cadences or kernel configuration. Features shipping in kernels newer than 5.15—like expanded btrfs capabilities, new memory management options, or state-of-the-art security modules—simply aren’t available except via full-blown VMs, either in Hyper-V or via third-party software like VirtualBox.
There’s also occasional friction around system-level daemons and tightly coupled security or performance tuning scripts, which sometimes behave unexpectedly under the containerized, hybrid WSL2 architecture.
Despite these gaps, feedback from developer communities suggests that the convenience and performance benefits usually outweigh these concerns. The ability to flip instantly between Windows and Linux—sharing files, scripts, and environment variables at native speeds—is game-changing for cross-platform workflows.
All official WSL2 distributions inherit the same Microsoft-maintained kernel. For those seeking bleeding-edge kernels, only direct VM installs or bare-metal Linux will suffice. Still, the addition of Fedora 42 introduces a style, philosophy, and package set that broadens the appeal of WSL2 to both open-source contributors and those looking to test the future of Red Hat-derived systems.
For most developers—especially those who rely on up-to-date userspace tools rather than kernel innovations—WSL2 with Fedora 42 strikes an ideal balance of speed, convenience, and compatibility. For advanced users needing the latest hardware support or kernel features, using Fedora under VirtualBox or Hyper-V remains the best bet, at least until Microsoft accelerates its kernel update cycle.
Regardless, Fedora’s arrival on WSL2 signals a more open, collaborative era for Linux on Windows. It breaks down silos, raises expectations for what “cross-platform” can mean, and ensures that the best of both worlds—Microsoft’s robust desktop and Fedora’s open-source innovation—are now just a click away. As more users adopt this setup, both Fedora and Microsoft are likely to evolve their offerings, making WSL2 an ever more compelling solution for developers, testers, and IT professionals alike.

Under the Hood: How WSL2 Delivers Fedora
WSL2 offers deep integration between Windows and Linux distributions, and that’s both a strength and a limitation. Unlike pure virtualization or native dual-booting, WSL2 creates lightweight containers employing a shared, Microsoft-customized Linux kernel. This approach delivers exceptional performance for command-line utilities, cross-platform development, and scripting, while giving users direct filesystem access between Windows and Linux.Yet, there’s a trade-off: the kernel version running under WSL2 is centrally managed and updated by Microsoft—not by the distribution maintainers. As of Fedora 42’s WSL2 launch, the kernel in use is 5.15.167-4-microsoft-standard-WSL2, a long-term support (LTS) release originally published in 2021. Despite Fedora’s reputation for living on the edge with cutting-edge packages, the system userland (the set of software and utilities shipped by Fedora) is now being layered atop an older, static kernel image.

The Fedora wiki and documentation are transparent about this compromise. WSL2 distributions operate as containers, sharing a uniform hypervisor-kernel platform rather than supplying their own kernels. For users whose workloads hinge on updated kernel modules, filesystems, or the bleeding-edge features Fedora usually provides, this could be a significant constraint. While the
wsl --update command offers a pathway for updating the WSL2 kernel, as of this article’s writing, that still points to the 5.15 LTS series.Advantages of Fedora 42 on WSL2
For many, this kernel compromise is well worth the benefits Fedora 42 offers under WSL2:- Seamless Development Lifecycle: Fedora has long been a favorite with developers, upstream-focused engineers, and those keen to test the latest open-source stacks. Having direct command-line and environment parity between workstation, cloud, and now Windows-embedded deployments streamlines build-test cycles.
- Fast Setup via Microsoft Store: Official support means easy, reliable installation from the Microsoft Store, complete with ongoing updates delivered through trusted channels. No more side-loading, no more risk of outdated or insecure custom images.
- Integration with Windows: WSL2 leverages Windows-native hardware drivers, networking, and filesystems. Fedora’s tried-and-true tools—dnf, systemctl (in limited scope), Podman, and others—can work in close concert with Windows file shares, scripts, and editors.
- Better Security and Maintenance: Official images reduce the risk of backdoors or supply-chain attacks, especially compared to fly-by-night community repacks.
- Expanding Enterprise and Academic Compatibility: Fedora’s arrival solidifies WSL2 as a genuine choice for Red Hat ecosystem shops, academic courses, and open source contributors comfortable with the Fedora way.
Notable Limitations and Points of Caution
Yet, WSL2—and by extension, Fedora 42’s implementation—comes with key limitations:- Kernel Version Stagnation: WSL2’s shared kernel means you’re effectively locked into the version Microsoft supports. This is fine for many CLI workflows, but advanced features—newer filesystems, hardware features, or kernel extensions—may not be available. For instance, as of the time of launch, Ubuntu running natively or in a Hyper-V VM can access kernel 6.14 or newer, but under WSL2, both Fedora 42 and Arch are restricted to kernel 5.15.
- Not a Full Systemd Environment: While WSL2 has made strides in supporting init systems like systemd, certain services and use-cases aren’t fully backed—the tight integration sometimes creates friction for processes that expect full Linux-system semantics.
- Networking and Virtualization Trade-Offs: WSL2’s networking stack and virtualization approach are performant and energy efficient, but not every package or networking scenario operates exactly as it would on bare metal. Some legacy or low-level workloads may require real or emulated hardware (such as in traditional VirtualBox, VMware, or Hyper-V VMs).
- Hardware Compatibility and Performance: Early reports note issues with certain imagery under Hyper-V’s Generation 2 VM mode—users found Fedora 42 would not boot using this option, though Generation 1 works (if slowly). This may reflect upstream issues or gaps in Microsoft’s implementation of newer UEFI boot workflows for Linux guests, and it reminds users that WSL2’s goals are not to replicate all virtualization use-cases.
- No GUI by Default: Fedora 42 on WSL2 is fundamentally about headless, command-line computing. While the Windows Subsystem for Linux now offers some GUI options, official Fedora integration in this space is a work in progress compared to Ubuntu or SUSE, both of which have more explicit Microsoft partnership tracks.
Practical Workflow: Installing Fedora 42 on WSL2
Getting started with Fedora 42 on WSL2 is simple for most Windows 11 users:- Ensure WSL2 is Enabled: Windows users need to verify that WSL2 is installed and set as the default version using
wsl --list --onlineandwsl --set-default-version 2in their PowerShell prompt. - Install via Microsoft Store: Search for “Fedora 42” in the Store, and hit “Install”. The process pulls down a vetted, signed distribution image directly from Fedora’s own maintainers.
- Initialize the Distro: On first run, Fedora asks you to create a user and set up your environment, much as you would in a fresh cloud instance or VM.
- Update and Personalize: Use
dnf updateto pull down the latest packages and then configure your development stack as normal.
The Developer View: When Does WSL2 Shine, and Where Does It Fall Short?
For web developers, sysadmins, data scientists, and students, WSL2 with Fedora 42 is almost transformative. You gain the flexibility of Fedora’s fast-evolving ecosystem with the safety and compatibility of LTS kernels. Integration is tight: you can runpodman containers natively, test Python or Ruby scripts with exactly the same toolchain as on a cloud VPS, and even use Visual Studio Code directly connected to your Fedora WSL2 instance.But advanced Linux kernel hackers or those building kernel modules may be frustrated by their inability to control update cadences or kernel configuration. Features shipping in kernels newer than 5.15—like expanded btrfs capabilities, new memory management options, or state-of-the-art security modules—simply aren’t available except via full-blown VMs, either in Hyper-V or via third-party software like VirtualBox.
There’s also occasional friction around system-level daemons and tightly coupled security or performance tuning scripts, which sometimes behave unexpectedly under the containerized, hybrid WSL2 architecture.
Despite these gaps, feedback from developer communities suggests that the convenience and performance benefits usually outweigh these concerns. The ability to flip instantly between Windows and Linux—sharing files, scripts, and environment variables at native speeds—is game-changing for cross-platform workflows.
