CCleaner - Quick Tour
Optimization and Cleaning
CCleaner has four main sections which can be selected using the big icons on the left-hand navigation panel.
This is the main feature of the program, which will allow you to optimize your system by removing unused and temporary files.
(It's important to point out that it does this without removing any files you'll still need!)
This is a more advanced feature which analyzes your computer's registry and fixes any problems that exist. (The registry is where Windows stores system settings.)
This section allows you to view and manage Installed Programs, check the applications that run at Start Up and also manage and remove System Restore points.
The Options section handles all the settings for how CCleaner runs.
