Introduction to CCleaner

If you’ve never used CCleaner before, don’t worry – it’s very easy to get started. Just download the program from the official website and install it on your computer. Once you’ve done that, launch CCleaner and you’ll see a screen like this:

The left-hand side of the CCleaner interface is where you can select which areas of your system you want to clean. The options are divided into two main sections: Windows and Applications. Under Windows, you can choose to clean up your system files, temporary files, recycle bin, etc. Under Applications, you can choose to clean up your web browser (Internet Explorer, Firefox, Chrome, etc.), media player (iTunes, Windows Media Player, VLC Player, etc.), office suite (Microsoft Office, LibreOffice, etc.) and so on.

To clean up a specific area of your system, simply click on it and then click the “Run Cleaner” button at the bottom of the window. CCleaner will then scan your system for all the files that can be safely deleted and remove them for you. It’s that simple!

If you want to clean up your entire system in one go, simply click on the “Clean all” button at the bottom left-hand corner of the CCleaner interface. This will clean up all the areas of your system that are selected in the left-hand panel.
