Free Registry Cleaner, Junk File Cleaner and Windows Optimizers for Windows 10/8/7

You are probably here because you are looking for a free registry cleaner for your Windows 10/8/7 computer. Before you proceed, you need to know a few other things. Microsoft discontinued their own registry cleaners like RegClean, RegMaid with Windows XP onwards, and also its Windows Live OneCare registry cleaner more recently. While the question, whether registry cleaners actually make a Windows PC run faster is a hotly debated question, the fact remains that registry cleaners are one of the most used Windows software.Free Registry Cleaner

Apart from registry cleaners, optimization suites are also very popular with Windows users. All of us want our Windows PC’s to be running in top condition. While you can always use some tips to make Windows faster, many prefer to use a Registry Cleaner or a Windows optimization suite to keep their computer running smoothly.

This article will cover 10 Free Registry Cleaners and Windows Optimizers that will help your PC running smoothly.

Free Registry Cleaner, Junk File Cleaner & Windows Optimizer

1] CCleaner: CCleaner is one of the most popular and probably the safest registry cleaners available. The tool allows you to clean up your Windows Registry, Junk files, History, Privacy data, etc. – and offers some tools to let you control your start-up programs.

While this cloud-based tool has not caught the fancy of many Windows users, it does take a novel approach to keeping your Windows computer in lean, mean and fighting-fit condition.

Well, this was our list of some recommended free Windows registry cleaning and optimization system utilities. But I am sure there may be much more such! Before using such tools, it is always a good idea to quickly create a system restore point first or back up your Windows registry, just to be on the safe side.

You may be interested in knowing that generally speaking, Microsoft does not support the use of Registry Cleaners in Windows.

Do share and let us know and which one you use and recommend? We’d love to hear your views on them.

    registry cleaners are crap and will always be crap. You get no improvement only issues.

    Read what Mark Russinovich wrote about those useless tools:

    “I haven’t and never will implement a Registry cleaner since it’s of little practical use on anything other than Win2K terminal servers and developing one that’s both safe and effective requires a huge amount of application-specific knowledge.”

  2. I am completely aware of that link and it has been discussed here:

    Incidentally he has also said there: “So it seems that Registry junk is a Windows fact of life and that Registry cleaners will continue to have a place in the sysadmin’s tool chest, at least until we’re all running .NET applications that store their per-user settings in XML files – and then of course we’ll need XML cleaners”.

  3. Caleb

    You should try this free stand-alone registry cleaner. It is very fast and safe.

    Wise Registry Cleaner

  4. Pinky

    CCleaner is the only one that is truly portable. Although the others will ‘clean’ your registry, all of them write large amounts of entries to your registry before cleaning it – and yes, their entries remain untouched.

  5. Andwar

    Have been using CCleaner for years and haven’t seen anything yet to beat it!

  6. Regman

    Here’s one that is truly portable and gives your registry a through cleaning:

    Argente Registry Cleaner –

    I just ran it on my machine after I used CCleaner (rebooted) and it found almost 10,000 entries that CCleaner missed. My Win7 Slate PC is running much faster now.

  7. Star51L

    10,000? And you trust that program?

  8. Pedel Pop

    You forgot to mention 360Amigo System Speedup and Glary Utilities, another good one-click system cleaner which is currently being used by millions of people worldwide. They offer a wide range of system tools aimed for both beginners and experienced users. There are free & paid versions for both software.

    360Amigo System Speedup –
    Glary Utilities –

  9. I am not aware of that program, but just because it found 10K more entries, does not necessarily make it better. There was a moment in time when even CCleaner broke the Windows 7 context menu So one have to play very safe and take a conservative approach when cleaning the registry. Again in all honesty – whether using a Registry Cleaner really makes a computer run faster is a debatable issue, as has been mentioned in a link in the post above – but yes, it may be good good idea to keep your registry clean by using a cleaner occasionally.

  10. Regman

    It’s been 12 hours now along with two voluntary reboots – the machine runs great and the cleaner did not break anything. Argente is by far the best cleaner that I’ve found. My slate PC is running so much better now. You guys have to try this out – you won’t be sorry. I’m dumping my copies of Glary and TweakNow.

    vry nyc post..i rly likd it…xctly wt i ws lukin fr..

  12. Samit

    Auslogics Registry Cleaner for cleaning registry, Puran disk defrag for defragmenting harddisk, Quicksys registry defrag for defragmenting registry and Ccleaner to clean temporary files…..

  13. rover3500

    Then again if it was so certain that regcleaners do nothing,why is there so much discussion about it,there are pro’s and cons,elements of risk.Bit of common sense alot of the time.The amount of people I’ve fixed Pc’s for that have uninstalled a security product then straight away used a reg cleaner before a reboot so all the secutity program’s drivers etc don’t get uninstalled.My biggest tip with cleaners anyway is not to do this,always reboot 1st before using one.

  15. Registry cleaners and optimizers are an important aspect to keeping computers running effectively and efficiently. There are so many out there on the market, but you list some really great ones. What would you say are the two most important factors when picking a cleaner/optimizer?

  16. JonD122480

    You forgot to mention Advanced SystemCare, it’s probably the best free optimizer out there.

  17. Web QA Rat

    The one I like the most are the ones that require a downloader that hijack your computer or browser or install a bunch of useless software on your computer even though you decline them like Rizone’s Power Tools above.

  18. Chavirah

    JetClean have a BIG BUG, if you resist to keep free, any moment they erase ALL YOU HDD i have this BIG TROUBLE WHIT THEM!!!!! WARNING PLEASE!!!

  19. Chavirah

    Puran Utilities is awesome!!!!! and secure on SSD

  20. Gipanaul

    Basis on your advise I tried Puran Utilities. After scanning for empty folders, Puran found a lot of… By curiosity, I checked if some of them are indeed empty but I was very surprised to find that most of them still containing useful files on private drive!!! So, I decided to uninstall immediately this… “awesome” program. Other recommendations..!!?

  21. I see, the list is missing one of the best reg cleaner i know i.e. Registry Recycler. I think, you have not updated this article. Its time to update it and add my personal favorite in it.

  22. Steve Jordan

    Well the cleaner and uninstaller I use is Revo Uninstaller ..Check it out 🙂

  23. totalloy agree, the only one i use is CCleaner, and i use it(but not the registry cleaner)
    i use it for uninstall, remove crap from startup and scheduled tasks, i can do it all manually but it just puts it all in one place. and my computer is still working just fine without any of these

  24. Rodolfo

    exelentes programs to optimize pc.

  25. Ciprian

    I use RegCure Pro. It’s cheap and very effective. Short link here:

  26. Antreas Arkoudi

    ccleaner and iobit is the best i use them both for years now

    and never use registry cleaners is not good

  27. I am using Ninja TuneUp, it it better then ccleaner and registry cleaner. I am using it for long time and its trial version is free. Download its free trial version at

  28. Registry cleaners are good they flush out the useless stuffs from your PC but you have to use an efficiently working registry cleaner like Wise Registry Cleaner and Ninja TuneUp.

    My new (as of December) laptop has started doing weird stuff, and the space on my disk drive is almost all used up. I looked up solutions, but I still don’t know what to do. I am not really a tech-savvy person when it comes to computers, so does anyone have any suggestions? I just want it to get better.

  33. Philippe Nicole

    Hello though Microsoft says not to touch the registry?

  34. wahab

    I like your free registry it really work good thank you

  35. Lisa Green

    So, if they are useless, what is available in 2016 to speed up this mess? Can you recommend an alternative? I’m not a big fan of a cleaner unless you have a virus, you can manually scrub, you know where it’s hiding, and have no other choice. My computer is slow as molasses however, and short of buying a new one, I’d like to know what I can do. Thanks for any shared advice 🙂 -Lisa

    I’m not sure if you completely understood what was being said. The programs mentioned above are not what is being deemed as “useless.” They are specifically referring to the “Registry Cleaning” aspects of said software. Many of the other tools that they come with can be incredibly handy & beneficial. Especially a solid system cleaner (such as CCleaner – just stay away from the Registry Cleaner portion).

    For optimal system performance, just make sure that you only install programs that you need. Never keep junk and/or bloatware lying around. Under our Windows Customization settings, make sure you have it “set to best performance” and stay away from all of the “eye candy” settings & features, as these can knock a pretty big chunk out of your performance rating. Run “msconfig” and check your ‘Startup’ tab. Make sure you uncheck any & everything except the items that you absolutely MUST need to run immediately as your PC boots up. Keep a top-tier Anti-Virus (Avast, BitDefender, etc) and a top-tier Malware Fighter (Malwarebytes, Emsisoft, etc) around to make sure your system stays disinfected. Aside from that, there isn’t much else you can do – as, unfortunately, there are no top-secret programs or tweaks that can make a slow machine turn into a fast one. Your optimal speeds are both determined and limited by your specific hardware. If you want to get fancy and squeeze every last drop out of your system, search google for “Services to stop to increase performance.” Just be sure to pay close attention to what you will be turning off, as fiddling with the wrong services can quickly put an end to your fun…. as well as your entire operating system. In other words, only turn off the services that: 1) You have seen on a list of services that are known to be safe to turn off & disable, and 2) You know you do not and will not need in the future. With that being said – disabling some of the benign + resource heavy services can most definitely improve your system’s performance.

    That’s all I can think of for now. If I come up with anything else I feel would help you, I’ll be sure to come back and update this thread. I hope I was able to provide you with some helpful information. Have a wonderful day, Lisa.
