What is CCleaner?
CCleaner is a system optimization/cleaning tool. It removes unused files from your system, allowing Windows to run faster and freeing up valuable hard disk space. It can also clear your internet history and act as a fully featured registry cleaner. CCleaner is fast (normally taking less than a second to run) and contains NO spyware or adware!

The software tries to install Avast too - Spyware, runs in background and collects information to send to Avast. Background mode can be disabled, but gets re-enabled on each run - Shows pop-up system wide ads from time to time

users of windows 8 or newer, should never clear the registry! If you try to clean registry, then your boot will slow down.

hey I was curious, last year I downloaded Ccleaner for an old computer, but recently I just purchased a new laptop, and it is windows 8...What do you suggest as an alternative, if it happens to slow down?
thanks, JJ

I suggest the new CCleaner with the Pro features, like monitoring browsers. It's really cool app and helps to keep privacy and security in higher standards. Suggestions for your laptop "iobit-uninstaller" to remove unwanted pre installed apps. "Haozip" for rar zip isos and more! The best thing for anything compressed. Jdownloader 2 BETA to download anything you want from the web (BE CAUTIOUS press DECLINE to the software he propose to install during the setup, READ EVERY SINGLE ACCEPT)

CCleaner is a freemium computer cleaning tool that will not try to break your computer like most other software cleaners tend to do. I have been using CCleaner since 2011 and I have not found any difficulty using the software itself. However I will note that there have been many problems associated with the delivery of this tool. For example, the installation process.
Since 2011, I have seen that the previous installments of the program have undergone a slew of post installation offerings, such as useless toolbars, annoying search engines, and web browser installations, all of which may or may not have been installed voluntarily. CCleaner has had a previous problems with customers complaining about secret installs of web browsers, and toolbars, and have been supposedly fixed by an opt-out option. To avoid such mishaps, I recommend downloading from the main Piriform servers in which the software is hosted and nowhere else.
There are currently two versions of CCleaner. The Windows executable file, and the Windows portable .zip compressed file. To make a regular install of the software, just go to the main CCleaner website and proceed to the download. As for downloading the portable .zip, you must use your preferred search engine to find the webpage of the download. Search "CCleaner portable" and you should be able to find the web link where the download is located. Make sure that the website is authentic and official!
The software, as I see it, has improved features and other features that I think sucks.
The Goods (In my opinion)
You have the regular custom clean, registry clean, and tools options
There is a "one click" option called "Easy Clean". Self explanatory and very quick to execute.
There is a "Software Updater". Shows which mainstream(?) software needs updating.
And my favorite option, the "Disk Analyzer". I use this to hunt for files that needs deleting.
The Ugly (In my opinion)
It has an automatic auto-run service that starts every time you boot to your desktop. Resource killer.
When you close the program, it does not fully exit. There is a separate service that runs in your tray.
This has a "Skip User Account Control Warning" option, meaning everytime you run this program, it skips the UAC. _This is a terrible idea. Sure it may be annoying to start the program and have to press yes on the warning, but doing so prevents malicious code or people from hacking through this program and doing damage without you ever knowing! _
So I implore you to try out this tool! DL the .zip and if you like it, great!

Since Avast purchased Piriform CCleaner in July 2017, updates and installs cannot be trusted anymore. Reports of CCleaner updates installing Avast AV ... with default opt-in
CCleaner/Avast are phoning home with user data At first only PRO could be opted out, but more recently free CC now has opt-out. Avast have been ducking and weaving with CCleaner since they took over Piriform 10 months ago Portable CC has also been discontinued :(
What will they get up to next ? Very disappointing with this very long term favorite being treated as a cash cow by Avast
CC installer used to offer Google Toolbar *opt-in" but Avast have changed that to opt-out or you get their AV and consequences of 2 AVs on your machine. I can no longer trust Avast/Piriform ...
I don't like it, too many toolbars and other stuff.

More disaster by Avast/Piriform CCleaner Firefox users beware: CCleaner wipes Firefox extension settings by default (3-Aug-2020) (and Avast have known about it for months)
In the Bundleware warning message, there is written : > Background mode can be disabled, but gets re-enabled on each run.
Honestly, on Windows, you can disable the background mode without getting re-enabled on each run. I use Ccleaner since several years on many computers. This comment seems wrong.

It used to be one of the best free software out there.... until Avast acquired it. Such a pity. It's worth your time to find some better alternatives like Bleachbit which is free and open source software.

The end of a dynasty :(
Just use slim installer or portable version from the build page and that's it... https://www.ccleaner.com/ccleaner/builds
