We like CCleaner and we liked it when it was called crap cleaner too.
This program will help clean up unneeded temp files.
It will also clean up registry errors by deleting entries that point to empty files in the registry.
We use it regularly.
Start by downloading the program.
Double clicking on the .exe file will open a menu for you to install from.
As you install it will ask if you want to set Google Chrome as your default browser,
We don't. We uncheck the offered option.
When you install it will ask you if you want it to scan for cookies
these are used to keep login details for the sites you sign in to.
If you want to log on to sites you visit regularly without having to remember
user names and passwords you should do this.
You can also save cookies you select when you run the program as you will see in fig.3
