If you ever need a truly professional system optimizer that effectively scans your system, detects all possible files and registry entries that clog up your computer or compromises your privacy, and cleans them up in a fast and efficient way, CCleaner Professional is an excellent option to consider.

Wrapped up in an attractive, modern, and intuitive interface, CCleaner Professional offers you all the features and tools you need to keep your system clean, free from unnecessary files, and at the top of its performance. Junk files, temporary files, files left behind by uninstalled programs, cookies, broken Registry entries, duplicate files, memory dumps, log files, etc., litter your system, slow it down, and may compromise the privacy of your browsing habits and other sensitive information. Divided into three main categories – Cleaner, Registry, and Tools – this professional system-optimizing tool will detect through a thorough scan every single file that takes up your valuable disk space unnecessarily. Some of these files can also reveal important information about you and your browsing preferences that nobody else should know without your consent. Hence the importance of running a tool like CCleaner Professional regularly. Though the program comes without a scheduler that might automate these processes, its real-time monitoring tasks somehow compensate that lack.

The scan processes that analyze your disks, your Windows Registry, and the applications installed on your PC are fast and comprehensive. The reports generated by these scans detail every single file that can be removed without harming your system’s performance and efficiency. However, you are free to browse through all these files – conveniently organized following different criteria – and choose which of them will go and which you wish to keep on your computer. The Registry scan checks up to fifteen types of obsolete or broken entries that may be slowing down your PC’s performance. Missing shared DLLs, ActiveX and Class issues, wrong application paths, unwanted “run-at-startup” programs, or expendable help files and obsolete software may make it difficult for your system to keep an efficient and compact Windows Registry.

CCleaner Professional comes with a set of useful features to complement its cleaning tools. Thus, you will find an uninstaller that will get rid of unnecessary programs and the files and traces some usually left behind; a startup manager to help you decide which programs launch at startup and which won’t; a disk analyzer that will tell you which files are taking up too much space and the type of files your drives are holding; a duplicate finder, or a drive wiper, that will erase the contents of the free space of your disks in a secure way.

All of these features and tools are fully customizable. This high level of flexibility, together with the program’s proven efficiency make CCleaner Professional one of the most popular system optimization tools in the market, and probably one of the most efficient ones also.
