How to use CCleaner to free up PC storage and boost performance

Here is a 190-word summary of the key points from the article: CCleaner is a popular system optimization tool for Windows that has been downloaded nearly 3 billion times worldwide. The free software allows users to quickly clean up their computer's storage and boost performance with just a few clicks. The main features include a "Health Check" that scans for unnecessary files to delete, an "Advanced Cleanup" section to selectively remove data, and various other tools like uninstall management, registry editing, and disk space analysis. Users should be cautious with the registry cleaner, as it carries some risk. While the free version provides solid functionality, the paid CCleaner Pro adds extra features like a performance optimizer, driver updater, and software updater. However, free alternatives exist for these advanced capabilities. The mobile app version of CCleaner also provides similar cleaning capabilities for smartphones. Overall, the free CCleaner software is a reliable way for Windows users to free up storage space and improve system performance with minimal effort. The paid Pro version may be worth it for some users, but is not essential for basic system optimization.
