Operating systems, infrastructure, emulation, and technical history.
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.
Configuring Docker Desktop to use WSL2 as its backend, integrating specific distros, and verifying containers run on WSL2's real kernel, not a separate VM.
