How to download, install and update CCleaner in Windows XP, Vista, 7, 8 and 8.1

While Windows Disk Cleaner does quite good job at removing some temporary files, there are probably more non-Microsoft programs on your computer that have some leftovers and unneeded stuff on your computer. Also, every user tends to install, upgrade and uninstall software, and this might leave many unnecessary entries in Windows Registry - a place where all information about hardware (monitor, sound card, video card, mouse, etc), software and user settings is kept. When registry contains entries to programs and files that do not exist anymore, Windows might start slower or display errors.

CCleaner (also known as Crap Cleaner) is a free program for cleaning up such temporary files and unneeded settings in Windows registry. It can also detect and remove duplicate files, securely wipe free space or whole drives, manage Windows startup items and web browser add-ons. Since version 4.18, CCleaner has a real-time monitoring tool that offers to clean up temporary files from time to time.

There is also Android version of CCleaner available.

You might or might not see an offer to install some other software after clicking the Install button. In my case, it has randomly been Google Toolbar and/or Google Chrome. Do not install any software you do not really need or know much about. The word "Free" means nothing useful in such cases! Laughing
