Introduction
In Windows, uninstalling an application doesn't always mean completely removing it.
Between residual files, forgotten registry keys, and persistent trackers,
the system often ends up cluttered.
Gaël, from the Simple et Gratuit , presents
BCUninstaller , an open source, free and open uninstaller,
which does what Windows does not: deep clean .
1. Why a dedicated uninstaller?
When you uninstall a program via the "Apps and features" menu in Windows,
only the main components are removed.
Settings, history, customizations, and even some trackers remain hidden in the system.
- "Ghost" programs continue to consume resources;
- The Windows registry becomes bloated;
- And sometimes, private data persists.
👉 BCUninstaller fixes all of that.
2. Free, lightweight, and portable software
BCUninstaller is:
- 100% open source , available on GitHub;
- Compatible with Windows 7 and later versions ;
- Available in installable or portable version ;
- And entirely in French .
It only requires .NET 4.0 and a few hundred MB of RAM.
It works equally well on hard drives and SSDs.
3. Installation and first steps
- Download the program from Fosshub, SourceForge or directly from GitHub.
- Choose between standard or portable installation.
- Select the language (the software detects it automatically).
On first launch, an interactive tutorial helps you discover the main functions:
sorting, filters, displaying programs, etc.
4. A complete and secure uninstallation
BCUninstaller scans your system to detect:
- The installed programs;
- Orphan components;
- Unnecessary registry keys.
During uninstallation, you can:
- Create an automatic restore point ;
- system restart
- Remove residual files (registry files and keys);
- Simulate the uninstallation if you want to test it risk-free.
💡 This is the kind of feature that even paid uninstallers often forget to include.
5. Clear and practical interface
The interface allows you to:
- Sort software by size or installation date;
- Uninstall multiple programs at once;
- See which software takes up the most space;
- Kill active processes before deletion.
You can even do an online search to check if a program is safe before deleting it.
6. The alternative to Revo and other paid tools
Gaël often recommends Revo Uninstaller , which is very effective but partially paid.
BCUninstaller, on the other hand, offers comparable—or even better—performance at no cost.
And since it's free, you can even read the source code to understand how it works.
Conclusion
If you want to keep your Windows clean, stable and free of ghost files,
BCUninstaller is an indispensable tool.
Free, transparent and lightweight, it proves that free software can compete with the best paid software.
➡️ Download it directly from GitHub and keep it on your spare USB drive.
