for using CleanUp!
Go to Start > All Programs > CCleaner > CCleaner.
You should see this window. Click on Analyze. If you see some files
that you don't want CCleaner to clean, untick one of the boxes. If
you want a pretty clean system, but don't mind it being slow, you
can tick the Old Prefetch data box as well.
After analyzing and you are sure that you want CCleaner to clean
those files, clean on Run CCleaner.

In this Application tab, it list some of the applications that are
installed and files that can be safely cleared. Do not tick the
Saved Form Information box if you don't want to retype your
password the next time you log in.
