Windows has a tendency to get a bit messy after time, resulting in slowdowns and software crashes. This is why there are so many registry cleaners out there, today I will have a look at the famous CCleaner which is a completely free tool designed to improve windows performance. CCleaner does this by deleting files that you don’t need and removing invalid entries in the registry. After running CCleaner you can expect to have a faster and more reliable computer, you’ll even get more disc space!

Lets start with the developers description of CCleaner:

CCleaner is the number-one tool for cleaning your Windows PC. It protects your privacy online and makes your computer faster and more secure. Easy to use and a small, fast download.

Sounds good, right? Lets have a closer look on what CCleaner actually cleans:

Temporary files, history, cookies, download history, form history.

Google Chrome

CCleaner – The crap cleaning part

The most important features  for speeding up Windows would be the Windows clean up and registry cleaner. In addition frequently used programs like web browsers are cleaned by CCleaner, this is because they tend to collect a lot of garbage over time. Deleting this garbage will also of course result in more free disc space. The first time CCleaner is run on a computer it might delete files for several minutes resulting in a nice speed up and several gigabytes of free disc space. After running CCleaner for the first time I would recommend running Defraggler to defrag your hard drive, this will take some time but will surly give you a performance boost as long as you aren’t running from a SSD.


CCleaner’s registry cleaner

CCleaner is designed from the ground to be safe and secure to use. It has
multiple levels of checks in place to ensure that it won’t delete any useful information or documents you may still need. The default configuration should be suitable for most of CCleaner’s users, but if you are an advanced user and know what you are doing you can make CCleaner delete even more crap from the registry. Just remember to do a backup!

Advanced features to remove unused and old entries, including File Extensions, ActiveX Controls, ClassIDs, ProgIDs, Uninstallers, Shared DLLs, Fonts, Help Files, Application Paths, Icons, Invalid Shortcuts and more…

Our Conclusion:

I have been using CCleaner for several years now, I think that CCleaner is getting better and better by every program update. Did I mention that CCleaner got an auto update function? There is a new CCleaner release every month so remember to update CCleaner to the latest version for best performance.

Cleaner is fast in use as long as you choose just to delete files, but if you choose the safe file deletion it takes much longer time, but this is normal as the files are overwritten several times. For normal users I would recommend just using the normal deletions method, but if you want your temp files to be gone forever, then go ahead, use the secure file deletion option.

The registry cleaner part of CCleaner might not be the best on the marked, but it’s mote than good enough for a normal Windows user. Remember that this piece of software is free! Available in 35 different languages.

    After going to the download page, on the right is the CCleaner download. On the left is another download button, that is for Registry Mechanic. Registry Mechanic will prompt for you to purchase if you run it and tell it to fix what it found, CCleaner doesn’t.

    What cookies for Google and Yahoo are not cleaned by CCleaner? Can I opt to delete them anyway? What are these cookies for?

    1. Kenneth Article Author

      As far as I know CCleaner deletes all cookies, but you have the option to not clear cookies for services like Gmail and Yahoo Mail.

    CCleaner is definitely as effective with Windows 7 as it has been with Windows XP. Just give it a try!

    @phillip: Read it more closelt, they offer you to pay for support, CCleaner itself is free.

    I’ve used CCleaner for years and love it. They have NEVER charged for the software, so some of you knuckleheads have obviously downloaded the wrong software. The link that Kenneth offered above is the one that I use. I plan on adding links to their website and possibly this one on my own Computer Repair website

    I want to add a tips and tricks section and possible start doing some reviews. CCleaner is awesome! just make sure you look on the top right side for download link. That’s the free one. Good Luck ;-D

    After I used CCleaner on my computer, including the Registry part, my computer no longer remembers the path when I go to save downloads. I have to manually go to where I want to save something every time, which can be frustrating and time consuming. Is there a way to get that back? Since it found about 155 errors, I did not go through every one of them, after I looked at a few I just clicked to fix everything. Help!
