Advanced Registry Clear is a free tool that scans the Windows Registry for invalid, leftover, and junk entries and cleans them out when you tell it to. It's designed to be easy enough for beginners and infrequent PC users yet provides enough information about the files it targets for advanced users to choose which files to clean and which to leave. However, as with many such tools, the "free" part only goes so far.
Advanced Registry Clear's colorful, easy-to-navigate interface is fairly typical of free system cleaners based on premium products, with a large Scan button and registry clean, privacy sweep, junk file removal, and optimization tools that work much like other tools we've tried. Under the program's Settings, we could deselect check boxes for file types we wanted it to ignore, configure automatic scans, and choose other options. Under Utilities, Advanced Registry Clear bundles a variety of extras, such as a File Pulverizer, a Startup Manager, and disk maintenance utilities. We clicked a Help link, which opened a Web-based support page, but it mostly dealt with how to buy and register the premium software. Next we clicked the Scan button to initiate Advanced Registry Clear's primary cleaners, which returned a variety of problems to be fixed. We reviewed the selected files, and there seemed to be nothing risky or dangerous; mostly missing shortcut links and the like. A pop-up asked us if we wanted to repair the problems the program found. Since that was the whole point, we clicked the Cure button. Advanced Registry Clear fixed five problems, stopped, and presented us with a pop-up informing us that we'd have to Go Pro (buy the premium software) to fix them all.
If you're looking to buy a registry cleaner, you can certainly give Advanced Registry Clear a try. If you're looking for a free registry cleaner and system optimizer that's not only fully functional but effective, keep looking.
