CCleaner is a free Windows optimization tool that blitzes clutter and unwanted files from your computer, leaving it in tip top condition and faster than ever.
Not only does it delete temporary files and empty your Recycle Bin, it also clears out cookies from web browsers, cleans up leftovers from uninstalled programs, and deleted unused registry entries.
You can also use CCleaner to manage the programs that run when your PC starts up, and uninstall any that you don't use.
Why you need it
If you've ever despaired at the slow speed of your computer, it could be time for a system clean out. That's because the more you use your PC, the more clutter it accumulates. Temporary internet files, cookies and redundant files can all clog your machine up and leave it running about as fast as a sloth in slo-mo.
That's where CCleaner comes in. This handy little program analyses problem areas and, with your permission, banishes files that have reduced your computer to a crawl. It's remarkably thorough and can delete gigabytes of unnecessary and unwanted files on its first run.
But don't worry, it's also particularly smart. It steers well clear of important system files, and avoids cookies that look like they contain login information (unless you say otherwise), so you won't have to type out your passwords all over again. It also shows you exactly what it plans on deleting before it starts, so you know what to expect once you set it on its way.
