Most Windows system utilities and cleaners on the market today suffer from two main issues: they consume hundreds of megabytes of RAM running on bulky Chromium wrappers, or they arrive bundled with intrusive telemetry and adware.
I decided to take a different approach and build PC Tweaker natively from scratch.
The Stack: Rust + Tauri
Instead of packaging a heavy web browser instance, I used:
- Rust backend: Handles low-level Windows API interactions, memory cleanup routines, and background process management safely and deterministically.
- Tauri runtime: Relies on the native WebView2 already present on Windows 10/11, keeping the final binary footprint tiny and idle RAM consumption negligible.
Key Focus Areas
- Latency reduction: Fine-tuning OS responsiveness and thread scheduling for gaming workloads.
- Transparent cleanup: Eliminating system and browser junk without corrupting registry structures.
- Zero bloat: No silent telemetry loops or bundled installers.
The project is live at pctweaker.app, and you can check out the releases on GitHub.
Would love to hear technical feedback from other Rust and systems developers on Windows optimization hooks!
