Frequently Asked Questions About CCleaner
Get answers to the most common questions about CCleaner download, usage, safety, and features
❓ Is CCleaner really free?
Yes! CCleaner Free is completely free to download and use forever. There's also a CCleaner Professional version with advanced features like automatic cleaning, real-time monitoring, and premium support for $29.95/year. But the free version is powerful enough for most users.
❓ Is CCleaner safe to use in 2025?
Absolutely. CCleaner is safe and has been trusted by over 2.5 billion users worldwide. While there was a security incident in 2017 (which was quickly resolved), Piriform has since implemented industry-leading security measures. The software undergoes regular security audits and receives frequent updates. Always download from the official website to ensure authenticity.
❓ Will CCleaner delete important files?
No. CCleaner is designed to only remove temporary files, cache, and other unnecessary data. It won't delete your personal documents, photos, or important system files. You can also review what will be deleted before cleaning and customize which areas to clean. CCleaner creates automatic backups of registry changes for extra safety.
❓ How much space can CCleaner free up?
The amount varies based on your usage, but most users free up between 5GB to 50GB on their first scan. If you've never cleaned your PC before, you might recover even more space. Regular cleaning (weekly or monthly) typically removes 1-5GB of accumulated junk files.
❓ Should I use the Registry Cleaner?
The registry cleaner can help fix broken registry entries and improve system stability. However, it's not essential for everyone. If your PC is running fine, you may not need it. CCleaner automatically backs up registry changes, so you can restore them if needed. We recommend running it occasionally rather than daily.
❓ Does CCleaner work on Windows 11?
Yes! CCleaner is fully compatible with Windows 11, as well as Windows 10, 8.1, 8, and 7. The software is regularly updated to support the latest Windows features and security updates. It works on both 32-bit and 64-bit versions.
❓ How often should I run CCleaner?
For optimal performance, we recommend running CCleaner once a week. If you're a heavy internet user or download lots of files, you might want to clean more frequently. The Professional version includes scheduled automatic cleaning, so you don't have to remember to do it manually.
❓ What's the difference between CCleaner Free and Professional?
CCleaner Free includes all the core cleaning features, browser privacy protection, and registry cleaning. CCleaner Professional ($29.95/year) adds automatic cleaning, real-time monitoring, automatic updates, premium support, and software updater. Both versions are safe and effective.
❓ Can CCleaner speed up my computer?
Yes! By removing junk files, disabling unnecessary startup programs, and cleaning the registry, CCleaner can significantly improve your PC's speed. Users typically report faster boot times (up to 40% improvement), quicker application loading, and smoother overall performance.
❓ Does CCleaner protect my privacy?
Absolutely. CCleaner removes your browsing history, cookies, search history, download history, and other privacy traces from all major browsers. This prevents websites and advertisers from tracking your online activity. It's an essential tool for maintaining online privacy.
