CCleaner Free: Free cleanup and optimization for Windows
CCleaner Free is a classic cleanup tool for Windows that can remove temporary files, browser data, and junk that slowly builds up on your PC. It can free up space and, in some cases, make your computer feel a bit more responsive—especially on older machines where storage is tight.
What is CCleaner, and what can you use it for?
CCleaner is built to fjerne unødvendige filer and clean up traces from browsers and apps. The idea is simple: fewer temporary files, fewer leftovers — which means more space and less clutter.
Typically, CCleaner Free helps you:
✅ Remove temporary files, cache, and log files
✅ Delete browsing history, cookies (optional), and download history
✅ Clear leftovers from uninstalled programs (to a limited extent)
✅ See what’s taking up space
It’s especially helpful if you frequently install/uninstall apps or if your PC has limited SSD space.
How CCleaner performed in our hands-on test
We tested CCleaner Free on a standard Windows 11 PC with multiple browsers (Chrome and Edge) and a couple of heavy programs installed. Installation was quick, but there’s one place to stay alert: during setup you’re usually shown offers for extra features/deals, and it’s easy to hit Next too fast.
During cleanup, the program was stable and fast. On our test machine a standard cleanup mainly freed up space (cache and temp files), while the “PC feels faster” effect was modest. That’s normal: on modern PCs, CCleaner is mostly a space-and-tidying helper, not a magic turbo button.
Is CCleaner safe?
The short answer: yes, if you download it from the official source and use it sensibly.
The long answer: CCleaner has a solid reputation for cleanup, but the gratis version today feels more “commercial” than before. You’ll typically encounter ads for Pro, notifications, and offers — which detracts from the experience.
Our recommendations:
- Always download CCleaner from the official site
- Avoid clearing cookies automatically if you want to stay signed in to your sites
- Skip aggressive registry tweaks unless you know exactly what you’re doing

Features you actually get in the free version
CCleaner Free is best for basic cleanup:
Cleaning files and cache
The classic job: temporary files, cache, and leftovers that add no value.
Browser data and privacy
You can delete history, cache, and cookies. Be selective, because removing cookies can sign you out of services.
Simple app management
You’ll typically get a straightforward view of installed programs, and some versions also include startup management tools. Useful — just don’t expect the same depth as dedicated Windows utilities.
When does CCleaner make the most sense?
CCleaner is most useful if:
- you often run low on space on your C: drive
- your PC is older and there’s a lot of software clutter
- you want to clear browser cache quickly without digging into Windows settings
If your goal is maximum performance in games or heavy applications, it’s usually more effective to check:
- what starts with Windows (startup apps)
- how full your SSD is
- whether you’re short on RAM
- whether you’re running heavy background apps
Alternatives to CCleaner (if you’re tired of pop-ups)
There are several alternatives, depending on what you’re trying to achieve:
- Windows’ built‑in Storage/Storage Sense: good for basic cleanups without extra software
- BleachBit: more hands‑on, often popular with users who want control
- Glary Utilities: an all‑in‑one suite, but with lots of extra modules
