CCleaner CCleaner is easy for beginners to use – just launch it and click the Run Cleaner button. But there’s a lot more you can do with it. This popular application for wiping temporary files and clearing private data hides a variety of features, from fine-grained options for tweaking the cleaning process to full drive-wiping tools.
Consider What You Delete CCleaner clears a lot of stuff by default. You might want to reconsider clearing the browser caches. Clearing these will free up some space and increase your browsing privacy, but frequent cache cleanings can slow down your web browsing. Erasing the thumbnail cache (under Windows Explorer) can also slow things down. Clearing it does free up space, but at the cost of recreating the cache later. Many other options clear most-recently-used lists (MRUs) in Windows and other programs. These lists don’t take up much space, but can be privacy concerns

Wipe Drives When Windows or another operating system deletes a file, it doesn’t actually wipe the file from your hard disk. Instead, the pointers to the files marks the file’s location as free space. CCleaner can help protect the files from being recovered by wiping the free space with its Drive Wiper tool.
While CCleaner does include a registry cleaner,I’d recommend against running it. TheWindows registry contains hundreds of thousandsof entries; removing a few hundred (at most)won’t give you an increase in performance.Registry cleaners can accidentally removeimportant registry values, however, so there’s riskwith little reward.
