Advanced System Cleaner is what you might call a jack-of-one-trade, with a mixed bag of tools designed to find and remove space-hogging files. A beginner-friendly launch console provides access to the components. Disk Analyzer displays charts that show which folders and files are consuming the most space; however, it doesn't let you delete files without switching to Windows Explorer. Duplicate File Finder finds dupes quickly but doesn't let you choose how to search for them (for example, by name, by size, or by content). The Registry cleaner performs quickly and provides a backup utility, but it doesn't alert you if any keys represent potentially harmful spyware threats. The Privacy Protector feature won't replace a full-blown security suite, but it can clean up your history from Internet Explorer, the Start menu, common Windows system areas, and a couple of third-party applications. You'll also find a Registry defragmentation tool. Piece by piece, the tools in Advanced System Cleaner don't exactly shine, but together they provide an effective way to keep PCs in good running order.
