In fact, most computer users never have a legitimate reason to run a registry cleaner. A lot of people are surprised to hear this as our answer, but it's true. Contrary to the online advertising pitches, the bad information from your neighbor, and perhaps your own belief prior to this moment, registry cleaning is NOT a computer maintenance task. We can not be more clear on this topic. A long time ago, registry cleaners were more often, and more correctly, referred to as registry repair programs because that's what they do — they repair certain kinds of issues in the Windows Registry that cause a very short list of computer problems. See What Types of Computer Problems Do Registry Cleaners Fix? for help figuring out what sorts of issues you actually should be trying to fix with a registry cleaner tool. Habits are hard to break, though, so we often get this follow-up question at this point: "Maybe registry cleaning is overrated, but what's the harm in running one every day/week/month/year... just in case?" Honestly, we'd go beyond overrated and say unnecessary. Why would you want to do any kind of maintenance that's completely unnecessary? Do you clean your smartphone screen with borax even though a bit of water and a microfiber cloth does the job? Do you soak your favorite book in soapy water to get the dust off when a quick wipe accomplishes the same thing? Analogies are helpful, but let's get to the specifics with regards to registry cleaning: For one, it's a waste of your time. You have work to do, viral videos to watch, fantasy football leagues to plan, etc. Whatever else you like to you use your computer for is a better use of your time than running a registry cleaner for no particular reason. Secondly, it's a waste of your computer's resources. Using your computer's hard drive, RAM, and CPU for legitimate purposes is why you have a computer in the first place, but there's no reason to wear out those pieces of hardware even minutes sooner than need be with registry cleaning. Finally, and most importantly, letting an automated tool mess around with one of the most sensitive areas of Windows. Are Registry Cleaners Safe to Use? Don't get us wrong. As we mentioned in the first section above, there's a time and place for registry cleaners, but it's certainly not a regular computer task anyone needs to do. Yes, running a defrag program is a great thing to do every so often because files get fragmented over time, but it's absolutely not the same with "errors" in the Windows Registry. If you haven't seen it already, take a look through our What Does a Registry Cleaner Do? for more on what these programs are for...and not for.
