Cleaning Temporary and Registry Files

CCleaner is a program we use when a computer is running very slow. It is free to install and quick and easy to use. Simply follow the instructions below to download, install, and run a temporary file clean on your computer.

Step 1)

Navigate to This is the official website for CCleaner and you should only download it from this source.

Step 2)

Locate the download option. At the time this article was written, the main page of the website from Step 1 had a green “Free Download” button, as shown in the image below.

Once you have this screen, you are safe to close the program. You can let a few months pass until you run the scan again, unless you notice your computer running slowly.

Step 8)

There is a more advanced scan that you can run with CCleaner. This scan will go through the computer’s registry files and remove unneeded files, including potential viruses that might be hiding in the registry.

To run the registry scan, click on the icon labelled “Registry” in the side panel.

You will be prompted to backup changes to the directory. This can be done at your discretion, but is not normally necessary. After you make your choice, you will then get a new prompt like the one pictured below.

You can go through each file one by one, or simply click on the “Fix All Selected Issues” box. For most general users, the “Fix All” option will be fine.

It is recommended you repeat the registry scan until it no longer finds any issues.
