Fast, Lightweight, and Modern Windows System Cleaner
Nimbus Cleaner is a powerful system optimization and cleaning utility built with C# and WinForms. It helps you free up disk space, wipe temporary caches, and keep your Windows machine running smoothly.
- 🧹 Safe & Deep Cleanup: Removes system temp files, log files, prefetch, and application caches without touching personal documents or browser passwords.
- ⚡ Centralized Engine: Optimized cleaning algorithms with robust error handling and automatic locked-file skipping.
- 🚀 Smart RAM Booster: Win32 API integrated memory optimization to reclaim standby physical memory safely.
- 🖱️ Context Menu Integration: Native Windows Shell right-click menu integration for instant file and folder cleaning.
- 🌍 Multilingual Interface: Fully localized across 14 languages with automatic Windows language detection.
- 🎨 Modern & Customizable UI: Lightweight Windows Forms interface with dynamic theme presets.
- 📦 Easy Setup: Comes with a multi-language Inno Setup installer for quick deployment.
Since Nimbus Cleaner is an open-source tool built by an independent developer, it does not currently carry an expensive digital code-signing certificate. As a result, Windows SmartScreen may display a warning on your first launch.
