RAM Limiter

---

📋 Overview

RAM Limiter is a legacy, lightweight Windows utility written in Rust with native Win32 controls (native-windows-gui). It periodically trims or caps the working set memory of selected Windows processes via SetProcessWorkingSetSizeEx.

Core Capabilities

• Hard Trim & Soft Limit — Trims process working sets to their minimum or caps memory at a custom MB ceiling (soft_limit_mb).
• Skip Focused Window — Automatically avoids trimming the foreground process to prevent stuttering in active games or apps.
• Process Triggers — Gates memory limiting to only run while specific target processes (e.g. games) are active.
• Process Picker & Icon Extraction — Real-time process memory viewer and native Win32 icon extraction.
• Telemetry — Cumulative page faults tracking and estimated disk write / paging statistics.
• Profiles — Save and switch between named presets (Gaming, Office, Idle).

⚠️ Disclaimer & Disk Wear Note

Periodically forcing Windows to trim working set memory moves memory pages into the Windows pagefile (pagefile.sys), freeing physical RAM at the expense of disk I/O. For modern process and memory management, please consider using ProcessHandler instead.
