In a recent article – Should You Clean The Registry – I made the point that, while CCleaner’s registry cleaner has been proven to be safe to use, it errs so much on the side of safety that it is next to useless. I am not an advocate for cleaning the registry myself but this is merely an exercise to prove a point. Now let’s take a look at CCleaner’s registry cleaning function. I could go on comparing CCleaner with other junk file cleaners – such as PrivaZer, for example – but I can assure you the results are just as bad, if not worse, for CCleaner.

It’s been a little over a week since I last ran a disk cleaner on this system so, by my calculations, at the end of 12 months CCleaner would have missed around 16GB of junk files still clogging up the system. Near enough to double what CCleaner identified. And, invoking the Advanced Cleaner option identified a further 231MB for a total of 1054MB. Wise Disk Cleaner identified 823MB worth of junk files for deletion. I am performing analysis scans only, one immediately after the other, and on the exact same system in the exact same state (click on any of the images to enlarge):ĬCleaner identified 562MB worth of junk files for deletion. CCleaner vs Wise Disk Cleanerįirst off, a comparison between CCleaner and Wise Disk Cleaner’s junk file cleaning abilities. I am now going to revisit that topic and show you just how CCleaner compares when performing its core functionality. Way back in 2012 I wrote a series of articles comparing CCleaner’s effectiveness with a number of free alternatives and, in every case, CCleaner came out second best. I’ve been messing with computers for over 40 years, have been fixing and building computers for 25 plus years, and started writing about computers, technology, and software, in particular, some 15 years ago. Seems every time I write anything negative about the popular junk file cleaner, there are plenty of users prepared to jump to its defense.

CCleaner certainly has a faithful following.
