FluentCleaner — Classic & Modern Feature Update

Caution

⚠️ Avoid fluentcleaner[.]org

fluentcleaner.org is NOT an official FluentCleaner website and is not operated, maintained, or endorsed by me.

I strongly recommend not downloading or installing anything from that site.
Apparently, "trusted tech" in 2026 can mean googling an app and linking the first fake site that shows up. I recently found multiple major tech blogs doing exactly that with FluentCleaner.

There is only ONE official source for FluentCleaner:
https://github.com/builtbybel/FluentCleaner

If another website claims to provide an "official" FluentCleaner download, installer, build, or mirror, it isn't coming from me.
Hard to expect users to verify their sources when even the "tech experts" don't.

Credit where credit is due: Deskmodder.de is one of the few tech blogs that actually took this problem seriously and warned its readers about increasingly aggressive fake software websites distributing malware.

Thank you for doing the responsible thing and actually warning your readers:

Two editions, one cleaner

FluentCleaner is available in two independent editions:

Modern
The full modern Windows experience with WinUI 3, Windows App SDK, scheduled cleaning, AI integrations, Custom Cleaner, and the latest FluentCleaner features.

Classic
The old-school alternative built with WinForms and .NET Framework. Lightweight, compact, and increasingly close to feature parity with Modern.

Pick your poison.
Just make sure you get it from the actual developer
