Nexa MemKeeper (Portable)

SosomLab·SosomLab.NexaMemKeeper.Portable

Tray-resident memory optimizer for Windows - portable, no installer.

Nexa MemKeeper watches Windows memory from the tray and reclaims what is no longer needed. It is written in pure Rust on the Win32 API - no managed runtime, no UI framework, no external DLLs beyond the OS inbox set. This is the portable edition: no installer and no Programs and Features entry. Settings are written next to the executable under data\settings.ini, so the folder can be moved or carried on a USB drive; if that location is read-only, settings fall back to %LOCALAPPDATA%\NexaMemKeeper. Autostart is off until you enable it from the tray menu. Highlights: Top 5 popup on tray click; Task Manager-style process list with app grouping, live search by name/PID/window title, and kill process / process tree / thread; selectable cleanup areas; automatic cleanup on a usage threshold, on a schedule, or when Windows signals low memory. English/Korean UI. Free for personal and other noncommercial use; commercial use requires a paid license.
