Where CCleaner fits
Consider it when a specific cleanup task cannot be handled conveniently through built-in settings.
Check before you choose
Review each selected category and back up important data before applying a cleanup.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Identify the problem before installing a utility. File search, remote support, hardware inspection and bootable media preparation need different permissions and can affect the computer in different ways.
