What Is CCleaner?

CCleaner is one of the oldest and most popular system optimization tools. It’s designed to clean temporary files, remove cookies, and fix system errors that slow down your PC. Many users like CCleaner because it’s simple to use, even for beginners.

This makes CCleaner suitable for those who want an all-in-one cleaning solution with extra system tools.
