When it comes to keeping your system clean, there’s no shortage of tools on the market. Each one of them claims that their technology is the best in repairing and keeping your system efficient. CCleaner is one of these tools and in this review, we’ll find out just how good and effective is. A wealth of tools is provided by this system optimization tool, all nicely embedded into one convenient package. Let’s find out more about CCleaner and its features which have since wooed a huge following.


Designed to be a lightweight tool, CCleaner boasts a straightforward installation that will not pose you any problems. The 2MB setup kit warrants a fast download and a smooth installation. CCleaner was built for the PC platform and as a result, it works on the all available versions of Windows from Win98 onwards. Considered adware, the Yahoo! Toolbar is integrated into the CCleaner installation package. Besides this, CCleaner doesn’t come bundled with other programs.


You should be happy to find out that CCleaner has a clean interface that is easy to use and navigate. The icons are visible and the placement of the controls ensures that you will not lose any time fiddling about not knowing what to do. What is more, novice users will not have any problems with a registry fix, for example, and improving their system’s performance by cleaning their hard drives from all that unavoidable junk. With a good design and great functionality, the interface of CCleaner is certainly one of the tool’s greatest strengths.


With the sole purpose of optimizing your system’s performance, CCleaner makes sure that all the unused and temporary files are removed. As a result, your system will be faster, you will gain more performance as well as that valuable disk space. The following components of Windows can be cleaned: the URL history, cookies of Internet Explorer and Firefox, the Recycle bin, clipboard, Windows temporary files, Tray Notifications Cache, Custom Folders and many more. By using CCleaner, old files and settings left by standard Windows components can also be removed.

Well, do you know that many popular tools such as Safari ,Opera, Media Players, eMule, Kazaa, Google Toolbar, Netscape, Microsoft Office and Nero leave their temporary files and file lists on your hard drive? Thus, you lose disk space with unnecessary files. CCleaner will make sure that your system is performing at its maximum by deleting these files. Another useful feature of CCleaner is the registry cleaner. An advanced Registry Cleaner to check for problems and inconsistencies is used by CCleaner. Anything from file extensions and ActiveX Controls to Shared DLLs and Application Paths are cleaned by this efficient tool.

The drive wiping tool is another powerful feature provided by CCleaner. Keep in mind that it is a fairly nuanced tool that allows for multiple cleaning options. All the data from your hard drive will be wiped. CCleaner is a system optimization tool that’s jam packed with features but it doesn’t forget something very important: speed. It is a fast tool with excellent cleaning times. What is more, it is also safe and secure to use. You might worry that among all of the files that CCleaner removes from your system, an important folder will disappear. Multiple levels of checks ensure that any useful information or documents you may still need won’t be deleted. A nice feature is the multitude of supported languages. Available in 35 different languages, we can say that CCleaner is truly a universal tool.


More features for the Windows 7 OS would be welcomed. Besides this minor-at-best issue, CCleaner performs flawlessly.


If there’s one thing the software market doesn’t lack, it is system optimization tools. There are a lot of such software products out there. Let’s list some alternatives to CCleaner. The following tools fall into this category: Glary Utilities, TuneUp Utilities, Advanced SystemCare Free, BleachBit, Wise Registry Cleaner and many more.


All in all, CCleaner is an excellent system optimization tool that will surely make your PC faster and trouble free. If you are having problem with system slowdowns, tons of unnecessary files and cookies, then CCleaner is definitely recommended for you. I personally have been using it on a regular basis for a respectable period of time – the number of problems I have encountered with this software product is zilch!
