A real Linux kernel and userland running alongside Windows - architecture, integration, and daily use.
Working through Docker Desktop's specific WSL2 integration points, from backend mode to per-distro toggles, when containers fail with confusing errors.
Diagnosing whether high vmmem usage is a genuine leak or reclaimable page cache, and setting a deliberate .wslconfig memory ceiling that actually fits your workload.
Isolating whether a WSL2 networking failure is DNS configuration, VPN interference, or the networking mode itself, before reaching for a fix.
Confirming that /mnt/c's cross-filesystem overhead is the actual cause of slow WSL2 file I/O, then moving the project to fix it structurally, not cosmetically.
Deleting files inside WSL2 does not shrink the Windows-side .vhdx automatically. That is expected dynamic-disk behavior, fixed with diskpart compaction.
Working through WSLg's compositor, GPU driver, and RDP transport layers separately to isolate a blank window, a crash, or visual corruption.
WSLg runs a real Wayland compositor and audio server inside WSL, remoting individual application windows to Windows over RDP's RAIL protocol.
WSL's path from a cancelled Android-compatibility project through syscall translation to a genuine, Microsoft-maintained Linux kernel in a lightweight VM.
Exporting a WSL distro's entire state to a portable file, and restoring it later on the same machine after a problem or on an entirely different one.
A complete diskpart walkthrough for shrinking a WSL2 distro's .vhdx file after deleting large data, since Windows never reclaims that space on its own.
