WSL2's lightweight VM claims memory dynamically as Linux processes need it — but historically gave that memory back to Windows only reluctantly. Here's what's actually happening, and what you control via .wslconfig.
Task Manager shows vmmem consuming several gigabytes of RAM, even when you're not actively using WSL. Here's how to actually diagnose what's holding that memory, and how to cap it properly.
A complete walkthrough configuring a RAM disk with the built-in RAM driver — a fast, volatile drive letter backed entirely by memory, useful for temporary files and speeding up disk-heavy tasks.
A complete walkthrough building a batch-file boot menu that correctly manages memory-hungry TSRs — loading only what a chosen task actually needs, freeing conventional memory for everything else.
A container gets killed repeatedly with reason OOMKilled, even though the application 'shouldn't' need that much memory. Here's how to find its actual peak usage and set limits that reflect reality instead of guesses.
ZFS looks like it's eating every gigabyte of memory on the system. This is the Adaptive Replacement Cache working as designed — here's how to confirm that and tune it if it's genuinely a problem.
Why DOS memory is split into distinct regions with different rules, and how HIMEM.EXE and EMM386.EXE make more of it usable.
