CCleaner has been the go-to solution for millions of users since 2004, removing junk files, cleaning browser traces, and fixing registry errors that accumulate over time.
The free version provides comprehensive system cleaning without trial periods or feature restrictions - just download, install, and start optimizing.
System Cleaning and Registry Repair
CCleaner scans your entire system for temporary files, browser caches, outdated downloads, and application leftovers that waste disk space and slow performance.
The patented registry cleaner identifies broken references, invalid entries, and orphaned settings left behind by uninstalled software.
Unlike manual cleanup, CCleaner knows which files are safe to remove and which Windows components should remain untouched.
The Health Check feature provides instant system analysis with one-click optimization. It identifies junk files consuming storage, outdated software creating security vulnerabilities, startup programs delaying boot times, and browser trackers compromising your privacy.
For users who prefer granular control, the Custom Clean mode lets you select exactly which file categories to clean while preserving specific cookies, folders, or application data.
Privacy Protection and Software Management
Browser privacy protection covers Chrome, Firefox, Edge, Opera, and other major browsers. CCleaner removes browsing history, download records, cached images, saved passwords, and tracking cookies that advertisers use to monitor your online activity.
The Software Updater scans installed applications for outdated versions with known security holes, then downloads and applies patches automatically. Combined with the Driver Updater feature in the professional version, you get comprehensive system maintenance that keeps Windows running smoothly.
The startup manager reveals every program launching with Windows - including hidden services that consume memory without your knowledge. Disable resource-heavy applications to achieve faster boot times and better system responsiveness.
The built-in uninstaller removes programs completely, eliminating leftover files and registry entries that Windows' native uninstaller misses.
Privacy Concerns and Open-Source Alternatives
For users concerned about the Avast acquisition in 2017, CCleaner continues operating as a standalone product with its own development team.
The free version contains no advertisements or bundled software during installation when you use the "Slim" installer available from the official website.
Privacy-conscious users who prefer open-source alternatives should consider BleachBit, which provides similar cleaning capabilities with full source code transparency and zero telemetry.
What's New in CCleaner 7.0
Version 7.0 introduced a completely redesigned interface with light and dark theme options, ARM64 architecture support for modern Windows devices, and improved cleaning safeguards that warn before removing files from your Downloads folder.
The Temporary Uninstall feature now lets you specify how long applications stays temporarily removed before permanent deletion, giving you more control over what stays on your system.
Windows 11 Optimization Tools
Windows 11 users looking for deeper system customization should explore Win11Debloat for removing pre-installed Microsoft apps, or FlyOOBE for comprehensive debloating with a visual interface.
For official Microsoft optimization tools, Microsoft PC Manager provides one-click system cleanup directly from the Windows developers, though it offers fewer cleaning options than CCleaner.
Comprehensive Maintenance Alternatives
Power users who need more comprehensive maintenance capabilities should look at HDCleaner, which combines over 3000 automated cleaning functions including disk defragmentation, file shredding, and system benchmarking in a single portable application.
For focused disk cleanup with defragmentation capabilities, Wise Disk Cleaner offers similar functionality with scheduled cleaning automation.
Privacy-focused users should supplement CCleaner with dedicated tools like Glary Tracks Eraser, which targets activity traces from over 100 Windows applications, or Privacy Eraser Free for secure deletion that prevents forensic data recovery. Both tools complement CCleaner's browser cleaning with deeper application-level privacy protection.
For driver management beyond CCleaner's built-in updater, Snappy Driver Installer Origin provides completely offline driver updates using downloadable driver packs - essential for technicians deploying Windows systems without internet connectivity.
The companion CCleaner Browser offers built-in privacy features that reduce the need for frequent cleaning.
System Requirements and Download
CCleaner works on Windows 11, 10, 8.1, and 7 in both 32-bit and 64-bit configurations. The free version includes all cleaning, registry, and startup management features. Professional users gain automatic cleaning, real-time monitoring, scheduled scans, and priority customer support.
Download CCleaner and restore your PC's original performance in minutes.

Periform had a few very good products, then alas, sold them, (circumstances unknown).
Unfortunately, they were sold to Pirates, who have been caught cheating, several times.
Keep ccleaner, free version, open and free of nag screens, that offer unnecessary functions, as that will ruin the product.
Offer new products, separately.
Learn how to market, your products, honestly.
Don't show your foot prints on the moon!

Software has worked well for a while, however: As of today (2/20/2025), it appears that CCleaner support (personal and business) has been taken offline.
Don't know what is going on.

I'd like to take up the cudgels for Crap Cleaner. Sure - the installer manipulates your Windows firewall to tunnel home and tries to trick you into things you don't need. Software and driver updaters are things with no real purpose and stink like the installer.
The new owners have deliberately made a crap program out of it! That's right! I still hear people say things like "Ahh, CCleaner - you'll ruin your system with it." I think to myself that anyone who manages to do that shouldn't think they're particularly clever.
Either the CCleaner version was out of date or the users were too blind or too stupid to use CCleaner correctly or not able to reboot Windows quickly. A reasonably secure Windows with a sober user has no problems with CCleaner!
CCleaner has been running portable and "clean" for a good 20 years. For a long time it was the only tool (apart from the console) that could uninstall a lot of bloatware from Windows XP etc. and if you wanted to quickly clean your registry of residues from installers and driver corpses, it was the tool of choice.
If you take a closer look, there were/are even more useful "extras" under Extras for free. Overwriting once is enough for the hard disk wiper. Just wanted to mention it.
Is Crap Cleaner a must have? Nope! But it is still useful to have it as a portable version.
