CachyOS provides a Windows Subsystem for Linux image. Its official guide, updated November 5, documents file-based installation and CPU-optimized packages.
This gives Windows users another Linux environment for command-line work. It should not be read as evidence that the complete CachyOS desktop experience, or its performance on a native installation, has been reproduced inside Windows.
What the installation includes
The documented method needs WSL 2 version 2.4.4 or newer. Download and open the project’s linked .wsl image, then launch it. Setup creates a sudo-enabled user with fish as the shell.
The x86-64 image selects optimized repositories where supported; this does not imply support for every Windows processor architecture. The guide recommends updating packages after setup.
The kernel distinction matters
The standard image uses Microsoft’s kernel, without CachyOS’s kernel, schedulers, sched-ext, boot manager, hardware-detection tool or zram.
Microsoft’s WSL documentation explains the architecture: WSL 2 runs a Linux kernel in a lightweight managed virtual machine, with distributions operating as isolated containers inside it. WSL can run Linux command-line tools, development languages and services while also allowing Windows and Linux applications to invoke one another.
For a developer or security practitioner, that makes this a way to try the distribution’s user-space packages alongside Windows. It does not establish a measured speed advantage over another WSL distribution. No independent performance testing was conducted for this article.
Choose the environment around the work: package availability, a repeatable setup and how files and tools interact with Windows. If a task depends on a particular kernel module, scheduler or hardware feature, verify that requirement separately before assuming results from a native CachyOS machine will carry over.
