This PC-cleaning application found it’s way to me via the BBC’s Click Online, and it’s the absolute best I’ve ever come across. It cleans out temporary files, and generally cleans up your system quick as a flash, as well as scanning your registry for errors, and fixing those at lightning speed. It’s absolutely excellent and completely free, so if you’re running Windows and it’s getting a bit sluggish or your hard-drive is filling up fast, download this and give it a go. It’s well worth it.
