01 / Problem
Fixing a slow Windows PC means jumping between Task Manager, the Services console, uninstallers and storage tools, with no shared context and no safety net.
02 / Role
Designed, built and released as a personal project: scope, Rust backend, interface, installer and update pipeline.
03 / Decisions
Four choices that shaped the build
- D1
Tauri 2 with a native Rust core
System calls live in Rust; the UI runs on the WebView2 runtime Windows already ships. The installer stays near 5 MB instead of bundling a browser engine.
- D2
The backend re-checks every destructive action
The UI confirms; Rust validates again before ending a process or removing anything. Critical processes are protected and Microsoft's built-in tasks excluded.
- D3
Verified self-updates
Updates arrive from GitHub Releases and are checked against a SHA-256 hash and signature before installing in place.
- D4
Elevation only where needed
Runs as a normal user; service control and the standby-list purge request Administrator rights. Every action is written to an activity log.
04 / Outcome
- Released publicly; v2.1.3 after the rename from Process Killer.
- Eight tools: processes, services, apps, startup & tasks, optimizer, storage, performance, activity log.
- Free, MIT-licensed; installs per-user or machine-wide.
