One button. All the cleaning.

Kaury Clean reviews junk files, startup apps, memory, disk and old downloads. Then it shows you a clear summary, and only cleans what is safe.

Your whole PC, in one app

Six sections. Nothing complicated.

Each section does one thing, and does it well. You see everything before deciding.

Cleanup

Windows temp files, update leftovers, error reports, app and browser caches, the Recycle Bin.

  • Windows Update
  • Chrome
  • Edge
  • Firefox
  • Brave
  • Spotify
  • Discord
  • Slack
  • Steam
  • Epic Games
  • VS Code
  • Adobe

My files

See what takes up space on your disk, find large files, duplicates (compared by content, not by name) and old downloads. Tidy your Desktop by type, and undo in one click.

  • Disk map
  • Large files
  • Duplicates
  • Old downloads
  • Tidying

Performance

The apps filling your memory, and the ones launching with Windows. Enable, disable, close.

Applications

All your apps with their size, sorted and searchable. Uninstalling goes through their official uninstaller.

Repair

Restore point, Windows repair, disk check, DNS cache, icons, Microsoft Store.

All features

Our principles

A cleaner that doesn't scare you.

No red alerts, no panicking counters. Kaury Clean shows you, explains, and lets you decide.

Nothing goes without you

You see every item before cleaning. Large files and duplicates go to the Recycle Bin.

Always reversible

Startup apps are disabled, not deleted. Tidying can be undone in one click.

No fake "RAM cleaning"

Windows already manages memory. Kaury Clean shows you the hungry apps and lets you close them.

No registry cleaning

It speeds nothing up and can break Windows. We skip it.

OneDrive respected

Files left in the cloud are never read, so never downloaded to your PC.

Windows' own tools

Repairs go through DISM, SFC, chkdsk and restore points. No home-made recipes.

Security, in detail

The difference

What a cleaner shouldn't do.

Many cleaners

  • Red alerts and "1,284 problems found" to scare you.
  • A "registry cleanup" that speeds nothing up and can break Windows.
  • A "free up RAM" button that slows your PC down right after.
  • A crippled free version, then a subscription.
  • Extra software slipped into the installer.

Kaury Clean

  • A calm, readable summary, in GB and apps, not in "problems".
  • No registry. Ever.
  • The hungry apps, shown. You decide whether to close them.
  • Everything is free. There's nothing to unlock.
  • A 1.6 MB installer that only installs Kaury Clean.

Free, but not without you.

Kaury Clean will never ask you for money. If the app helped you, here's how to help it grow, in thirty seconds.

FAQ

You might be wondering…

Is it really free?

Yes, completely. No paid version, no subscription, no ads, no account to create. Kaury Clean is a project by Kaury Studio, a Swiss design and development studio: the app shows what we can do, and we'd rather it helps as many people as possible.

Is the app in English?

Yes. Kaury Clean follows your Windows language: English, or French if your Windows is in French. You can switch anytime in About.

Windows says "Windows protected your PC". Is that normal?

Yes. The app is not signed with a paid certificate yet, so Windows warns you as a precaution. Click More info, then Run anyway. The Install page shows exactly where to click.

Can Kaury Clean damage my PC?

It's designed so it can't: cleaned folders are fixed in the code, recent or in-use files are kept, nothing is deleted without you seeing it, and repairs use Windows' official tools. It's all explained on the Security page.

Does the app send my data anywhere?

No. Its only internet connection checks GitHub for a new version. No statistics, no tracking, no account.

Do I need to be an administrator?

No. Kaury Clean starts without admin rights. Protected Windows folders are flagged and unchecked; a link lets you relaunch the app as administrator if you want to go further.

Which computers does it run on?

Windows 10 and Windows 11 PCs (64-bit). No Mac or Linux version for now.

How do updates work?

Each time it opens, Kaury Clean checks for a new version and offers to install it in one click. Your settings are kept.

And to uninstall it?

Like any software: Settings › Apps › Kaury Clean › Uninstall.

Ready to clean up?

Two minutes to install, one click to clean.
