A registry cleaner is a tool for Windows computers that attempts to tidy up the entries in the Windows Registry, which can get messy over time. The registry is a kind of map that tells the operating system where your software is installed, how to run that software, and what physical components are inside your computer.
Wise Registry is one of the few free Registry cleaners that you'll see get consistently recommended. It can backup and restore the Registry, clean according to a schedule, employ different cleaning levels, and create a Windows Restore Point before changing anything, to reduce the chance of the operating system being rendered unusable.
CCleaner is great at automating a lot of file cleanup activities, though we'd dial back its aggressiveness toward tidying up your browser cache and the Windows registry. A browser cache is useful for quickly reloading previously visited Web pages. And since it's a cache, it will just get gradually refilled if you delete all of its contents, so space savings is pretty temporary. CCleaner is also good because it works with older versions of Windows all the way back to XP, and it's frequently updated.
Unfortunately, free registry cleaners don't have a great reputation. Their interfaces can be confusing, or they may encourage you to clean everything in one click, which is just asking for trouble. A cleaner such as Registry First Aid avoids such pitfalls and even has built-in backup and restoration features. A license is $28, but you can try it for free.
