CCleaner is a very easy to use program that allows you to speed up the performance of your computer system by discarding all of the unused files, leftover installation tags, and general clutter that builds up inside any system that is used to access the Internet on a frequent basis.
Since any computer has a limited amount of memory available, allowing various programs to reserve portions of that available memory for their own exclusive use is one way in which systems become slower and slower. A CCleaner review frees up all this hostage memory for use by the general system.
It also allows you to clear out your Internet cache and dispose of unwanted programs and unused files. Best of all, it is very friendly towards those who know little about computer system configuration. Install it, tell it to get busy, and if it has any questions, it will ask you. Simple.
