Evolving at the pace of the market, CCleaner has not stopped improving its functionality release after release for the last 10+ years. A reference among the myriad of system optimization tools right from the start, this free utility can keep your PC free from all types of junk and unnecessary files, maintain your Windows registry in top condition, find duplicates, and restore your system, with just a few clicks.

CCleaner still stands out from all the other free system maintenance programs available for various reasons. The first and most important reason is that it not only works and delivers as promised, but it is also a safe tool. All system optimization tools pose a risk, especially when used carelessly on such sensitive items as the Windows registry. Well, with CCleaner you will not have to worry about your system’s integrity, regardless of the task you ask the program to perform. Though I recommend you to take advantage of the registry backup that the program offers before making any changes – you never know what may cause your PC to turn off in the middle of the optimization task – I have never needed to make use of that backup file in the many years I’ve been using CCleaner.

Other good reasons to use CCleaner are the high speed of its various optimization tasks, the thoroughness of the subsequent reports, the extensive information about your drives and their contents, the possibility of checking each issue before fixing it, its browser custom cleaning tasks, its startup manager, and that inner calm that results from knowing that your PC is in the best of hands.

The results of cleaning up your drives of unnecessary, duplicate, and all kinds of junk files are visible right from the moment the clean-up task is over. You will not only have a safer PC, but also a faster one in just a few seconds. For a continuous excellent performance, you’re advised to schedule CCleaner’s tasks.
