CCleaner Portable is a through cleaning program for the system, that improves the general performance of the system by eliminating unnecessary elements that its use generates.
Since this is a Portable version, we will need to paid special attention when we install it. When the installation process begins, the assistant will show us a window so we can choose the location (units) to place it.

We should select here the USB device where we will place the application so we can later carry it wherever we want.
The CCleaner Portable counts on 4 defined sections: Cleaner, Registry, Tools and Options.

Cleaner

The cleaner allows optimizing the system, since it eliminates the temporary files and those unnecessary ones that we no longer use. In addition to this, it eliminates all the signs and remainders that the Web navigation generates. In order to make a computer cleaning, we go to Cleaner, and we click on Executing the cleaner.
The Analyze button allows us to previously visualize what the CCleaner Portable is going to eliminate. After the analysis and just by clicking on Executing cleaner we will be able to eliminate the complete list of elements that it found.

Registry

This option allows to correct errors and old entrances in the system registry, optimizing a better system´s operation.

Registry clean

Inside Registry, we selected all the squares and we click on Looking for Problems.

When CCleaner Portable finishes the Windows registry it will show us the problems that have been found. By default, all these problems are selected for their cleaning, so only a click on the Repair selected button will be enough. It will ask us if we want to make a backup of the registry files. We click on Yes and we save it.
Then we click on Repairing selected again.

This way CCleaner Portable will fix all the selected problems.
