A real Linux kernel and userland running alongside Windows - architecture, integration, and daily use.
How Windows interop, mounted drives, networking, and enterprise policy actually shape WSL's threat model, and why it isn't a sandbox for untrusted code.
How the Microsoft Store WSL package decouples updates from full Windows releases, and why that affects available features, policy, and troubleshooting.
Why enabling systemd in WSL does not guarantee daemon permanence, and how services should actually handle WSL's own lifecycle events.
Why WSL cannot expose arbitrary USB devices directly, and how Windows binding, USB/IP transport, and Linux drivers fit together in usbipd-win.
How WSLENV selectively crosses environment variables between Windows and WSL and translates paths without corrupting separators or leaking secrets.
Each WSL2 distro lives inside a dynamically-expanding .vhdx file that grows with use but never shrinks back down automatically after deletions.
WSL distros reduce to a root filesystem tarball plus small registration metadata, which is exactly what makes import, export, and custom distros work.
Working through the specific, common causes of post-update WSL permission errors instead of reflexively reaching for chmod 777 or broad workarounds.
Why WSL2's internal VM clock falls behind Windows after sleep or hibernation, and the specific steps to force it back into sync reliably.
Working through Windows features, firmware virtualization, kernel version, and disk space in order to find why a WSL distro hangs or refuses to start.
