36 Free Registry Cleaners

A list of the best freeware registry cleaner and registry repair software

Registry cleaners are software programs that remove unnecessary entries from the Windows Registry. Registry cleaners are especially useful for removing registry entries that point to files that no longer exist.

Note: I've only included freeware registry cleaner programs in this list - in other words, only completely free registry cleaners. Any registry cleaner program that charges a fee of any kind (e.g. shareware, trialware) will not be included here. If a free registry cleaner has started to charge and I haven't removed it yet, please let me know.

Important: Free registry cleaners should only be used to troubleshoot specific issues. See How Often Should I Run a Registry Cleaner? for more on that. See my Registry Cleaner FAQ for more about registry cleaning and registry cleaner software.

CCleaner v5.35.6210.

CCleaner is the best free registry cleaner program I've tested. It's easy to use, prompts you to backup the registry before it makes changes, and includes a number of other useful tools.

Piriform provides both installable and portable versions of their free registry cleaner.

If you're set on using an automated tool to fix an issue you have that's caused by a registry problem, I highly recommend you use Piriform's CCleaner freeware registry cleaner tool.

CCleaner v5.40.6411 Review & Free Download

The CCleaner registry cleaner works on Windows 10, 8 & 8.1, 7, Vista, XP, Server 2008/2003, and older Windows versions like 2000, NT, ME and 98. 64-bit Windows versions are also supported.

CCleaner also works with macOS 10.6 to 10.11 El Capitan.

I tested CCleaner v5.40 using both their portable and installable versions on a 64-bit version of Windows 10 and Windows 8. More »

Wise Registry Cleaner v9.11. © WiseCleaner.com

Wise Registry Cleaner comes in very close to the other top rated registry fix tools. They've put together a fantastic free registry cleaner program.

Some big pluses for Wise's free registry cleaner include fast registry scans, scheduled scans, in place updates, and a clear separation between normal issues and those that are "unsafe," a feature I loved.

I don't like the fact that Wise Registry Cleaner pushes for a download of Wise Disk Cleaner at the end of the installation but it's easy to skip.

Wise Registry Cleaner v9.53 Review & Free Download

Wise Registry Cleaner comes in both installable and portable versions and can be used on Windows 10, 8, 7, Vista, and XP. 64-bit Windows versions are supported.

Screenshot of JetClean v1.5.0 in Windows 8
JetClean v1.5.0 (Registry Clean Scan Results).

JetClean, a free registry cleaner by BlueSprig, isn't one I see mentioned a lot but I found it to be very well done.

JetClean scanned the entire registry in just a few seconds and has a well-designed interface.

There are two major things I didn't like about JetClean. One: The number of cookies that JetClean considers keepable, by default, is a bit excessive. Two: It tries to install a toolbar, but you can decline it during installation.

I also don't like that there's not an easily available portable version of JetClean. Yes, one exists, but you have to "generate" one from within the installed version of JetClean on your computer. Strange!

JetClean v1.5.0 Review & Free Download

The JetClean registry cleaner supports both 32-bit and 64-bit versions of Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.

I tested JetClean v1.5.0 in Windows 10 and Windows 7. More »

Screenshot of Auslogics Registry Cleaner v6.2 in Windows 10
Auslogics Registry Cleaner v6.2.

Auslogics Registry Cleaner is another great registry cleaner program - it's probably one of the easiest registry cleaners to use out of all the tools I've tested.

My favorite feature of Auslogics Registry Cleaner is the colored severity rating for each category of registry area that the program finds that needs attention. This makes it really easy to figure out what might be having an impact on your computer.

If the several higher rated registry repair tools in my list don't give you the results you were looking for, give Auslogics Registry Cleaner a try.

Auslogics Registry Cleaner v7.0.4.0 Review & Free Download

Note: Before and after installing Auslogics Registry Cleaner, you may be asked to install other programs, but they're easy to deselect it if you wish not to install it.

Auslogics Registry Cleaner is compatible with Windows 10, Windows 8 and Windows 7 (64-bit and 32-bit), as well as 32-bit versions of Windows Vista and Windows XP.

I tested Auslogics Registry Cleaner v7.0.4.0 in Windows 10. More »

Screenshot of AML Registry Cleaner v4.25 in Windows 7
AML Registry Cleaner v4.25.

AML Registry Cleaner wasn't part of this list when I first put it together which was an obvious oversight on my part. AML's free registry tool has been the most frequent reader-suggested addition to these programs.

The interface is a bit "old" in style, but AML Registry Cleaner makes up for that with a solid registry search, lots of still-free additional tools, and a long history of not accidentally causing more problems.

AML Registry Cleaner v4.25 Review & Free Download

AML Registry Cleaner works on both 64-bit and 32-bit versions of Windows 10, 8, 7, Vista, and XP, as well as on some Windows Server operating systems.

Glarysoft's Registry Repair is another good freeware registry cleaner. Registry Repair is pretty simple to use and is a good option if some of the better tools aren't working out for you.

Registry Repair v5.0.1.87 Review & Free Download

Registry Repair works in Windows 10, 8, 7, Vista, XP, Server 2003, and older Windows operating systems like Windows 2000, NT, ME and 98.

jv16 PowerTools Lite is a freeware registry cleaner created by Macecraft, makers of several popular Windows utilities. jv16 PowerTools Lite was fast and found a similar number of needless registry entries as other tools in this area of my list.

No toolbars or other programs tried to install like with some other free registry cleaners.

Screenshot of Kingsoft PC Doctor v3.7 Registry Cleaner
Kingsoft PC Doctor v3.7.

Kingsoft PC Doctor is another registry cleaner embedded in a software suite.

This program is really easy to use, and the registry cleaner isn’t hidden away deep inside – it’s very easy to spot and run without any hassles.

One thing I didn’t like about Kingsoft PC Doctor is that you can’t schedule a registry cleaning at a later date, but you must instead run it manually. While this is the case, the manual scans do find a hefty amount of errors that are just a click away from being removed.

Kingsoft PC Doctor Free v3.7 Review & Free Download

Kingsoft PC Doctor is said to work with Windows 7, Vista, and XP, but I tested v3.7 in Windows 8 and Windows 10 without any issues. More »

Screenshot of EasyCleaner v2.0
EasyCleaner v2.0.

EasyCleaner is one of the oldest and most trusted free registry cleaners out there. The interface is a bit dated but it's a solid registry repair tool.

EasyCleaner took considerably longer than other registry cleaners to scan my registry but it did a fine job overall. I also liked how I wasn't asked to install a completely unrelated and useless browser toolbar during the install!

Both installer and portable versions of this registry cleaner are available.

EasyCleaner v2.0.6.380 Review & Free Download

The ToniArts website says that EasyCleaner works in Windows 7, Vista, XP, 2000, NT, ME, 98, and 95.

I tested EasyCleaner v2.0.6.380 in Windows 8 without any problems, but it didn't work correctly for me in Windows 10. More »

Screenshot of Argente Registry Cleaner v3.1.0.1
Argente Registry Cleaner v3.1.0.1.

Argente Registry Cleaner is a registry cleaner that walks you through a tiny wizard when you first open the program, which makes scanning for errors rather easy. It found about as many issues as the other programs in this list.

Registry backups are created automatically before removing any registry items, and an automatic maintenance mode does all the cleaning for you when your computer first starts, without any intervention on your part, which is really nice.

Undoing changes to your registry are really easy because you can either restore to an automatically created backup or make your own registry backup whenever you like, and then restore the registry from the Undo changes section of the program.

Download Argente Registry Cleaner v3.1.2.0 for Free

Argente Registry Cleaner works in Windows 10, 8, 7, Vista, and XP. I tested the most recent version of Windows 10 and Windows 7.

Note: The website for Argente Software is in Spanish, but this download link is to an English page. There's also a portable version of Argente Registry Cleaner that you can download from Softpedia. More »

Screenshot of the Advanced SystemCare Free v11 registry clean feature
Advanced SystemCare Free v11 Registry Clean.

Advanced SystemCare Free is one of IObit’s many freeware programs. “Registry Clean” is the utility in Advanced SystemCare that does the registry cleaning.

I find the registry scan to be very quick regardless of a number of errors the program finds. Advanced SystemCare is great for the non-tech-savvy because you don’t even have to view the results to repair them. Moreover, you could actually shut down or restart your PC when the cleaning is finished so you don’t have to worry about it.

One thing I don’t like about Advanced SystemCare is that if you’re after a particular cleaning type, like registry cleaning, you must first uncheck all the other options. All the features that are offered can be overwhelming and get in your way.

Also, the Deep Clean option requires the professional version of the program.

Download Advanced System Care Free v11.2

Advanced SystemCare Free works in Windows 10, 8, 7, Vista, and XP. I tested Advanced SystemCare Free v11.2 in Windows 10. More »

Screenshot of WinUtilities Registry Cleaner in Windows 8
WinUtilities Registry Cleaner.

WinUtilities Free is similar to Advanced SystemCare Free in that it has lots of other tools in addition to a registry cleaner. This program's registry cleaner is located in Modules > Clean Up & Repair.

This registry cleaner walks you through a wizard so you can select which areas of the registry to scan, and then you can choose to create a restore point before doing any cleaning. You can also export the list of errors to an HTML file.

One thing I like about WinUtilities Registry Cleaner is that you can setup the restore points to be removed automatically after a number of days. This helps keep your computer free from clutter while also providing you with some time to restore your computer back to the state it was in before you made the registry changes.

You can also restore the registry to its previous state using WinUtilities Registry Cleaner's automatic registry backups if you'd rather not restore your entire computer.

Download WinUtilities Free v15.1

WinUtilities Free works with 32-bit and 64-bit versions of Windows XP and newer Windows operating systems.

Screenshot of Eusing Free Registry Cleaner v3.2 Registry Cleaner
Eusing Free Registry Cleaner v3.2.

Eusing Free Registry Cleaner is another free registry cleaner. I frequently see references to this particular registry cleaner on other "top" lists but I didn't find anything spectacular about it.

Tip: Remember, a registry cleaner program is not a regular PC maintenance tool. Registry cleaners don't typically speed up your computer or provide any other day-to-day improvements to your PC. Registry cleaners should only be used to help solve specific kinds of problems.

Download Eusing Free Registry Cleaner v4.1 for Free

Eusing Software says that their free registry cleaner works on Windows 10, 8, 7, Vista, Server 2003, XP, 2000, NT, ME, 98, and 95. Portable and installable versions are available.

I tested Eusing Free Registry Cleaner v4.1 in Windows 7. More »

Screenshot of Cleanersoft Free Registry Fix v1.8 Registry Cleaner
Cleanersoft Free Registry Fix v1.8.

Cleanersoft Free Registry Fix is suspiciously similar to Eusing Free Registry Cleaner. That said, I'm not sure which freeware registry cleaner came first. The only reason I rank Cleanersoft's Free Registry Fix lower than Eusing Free Registry Cleaner is because this program took a very long time to scan the registry.

Of all the free registry cleaners that I tested, Cleanersoft Free Registry Fix found the largest number of registry entries that needed "repaired" but that doesn't necessarily mean it's the best program.

Download Cleanersoft Free Registry Fix v2.1 for Free

I tested v2.1 of Cleanersoft Software's free registry cleaner in Windows 10 but it also works with Windows 8, Windows 7, and older versions of Windows. More »

Screenshot of Free Window Registry Repair v3.1 Registry Cleaner
Free Window Registry Repair v3.1.

Free Window Registry Repair reminds me a lot of Eusing Free Registry Cleaner and Cleanersoft Free Registry Fix, so my assessment is similar. Try this registry cleaner if you need to, skip it and try a better one if you don't.

Registry scan time with Free Window Registry Repair was longer that with some of the higher rated registry cleaners but overall it looks like a decent tool.

Download Free Window Registry Repair v3.8 for Free

RegSofts Software's website says Free Window Registry Repair is compatible with Windows 8, 7, Vista, XP, and 2000, NT, ME and 98.

I successfully used Free Window Registry Repair to clean up the registry in both Windows 10 and Windows 7. More »

nCleaner v2.3.4.

nCleaner seems to be as good a registry cleaner as any other in this area of my list. It does all your standard registry cleaning, as well as some system cleaning.

I found nCleaner's interface to be a little confusing and I also don't like that it hasn't been updated in years. However, I felt compelled to at least include it here after receiving so many suggestions to add it to the list.

I tested the nCleaner v2.3.4 in Windows 10 and 8 and it seemed to work well, but it's only listed as supporting up to Windows Vista. More »

ACleaner v4.0.

ACleaner is another free registry cleaner. Although it looks a bit outdated, it works for the newer operating systems and does the job well.

The Windows registry is backed up automatically before fixing any issues, and restoring is just a couple clicks away.

There's also a startup manager and system cleaner that comes bundled with ACleaner, but the registry cleaner isn't difficult to find.

Download ACleaner v4.5 for Free

ACleaner works with Windows 10 down through Windows 2000. I tested v4.5 in both Windows 10 and Windows 7 and didn't find any problems. More »

Secure Eraser v5.000.

Secure Eraser is a program suite that includes a dedicated section for registry cleaning as well as for other tools like a file shredder.

Secure Eraser's registry cleaning function seemed to find most of the same errors and invalid entries as the other cleaners in this list.

After cleaning the registry, a results page will display in your Internet browser. This can be annoying, but it's easily toggled off from the settings.

Download Secure Eraser v5.001 for Free

Note: After setup has installed Secure Eraser, it may ask you to add another program to your computer, but you can skip over this if you'd rather not install the additional program.

Secure Eraser works with Windows 10, 8, 7, Vista, and XP. I tested version 5.001 in Windows 8. More »

Ashampoo WinOptimizer.

Ashampoo WinOptimizer has many different tools that come with the program, but "Registry Optimizer" is the registry cleaning function you’ll want to use.

The scanning is performed rather quickly with Ashampoo WinOptimizer, and it automatically creates a registry backup before any cleaning is done. It’s super simple to restore these backups in the event something goes wrong.

Ashampoo WinOptimizer sometimes displays a message when the program opens, which can get annoying if you’re using it often.

PCSleek Free Error Cleaner v3.46.

Free Error Cleaner is a registry cleaner by PCSleek with an easy-to-use interface. It combines a few other search parameters in addition to the registry, but they’re very easy to disable if you’re just wanting to fix registry issues.

Although the program looks outdated and simple, it backs up the registry before cleaning and seems to find about as many problems as the other registry cleaners in this list.

Free Error Cleaner is said to work in Windows 7, Vista, and XP. I tested v3.46 in Windows 8 without any issues. More »

Screenshot of Pointstone Registry Cleaner v4.10
Registry Cleaner v4.

Pointstone Registry Cleaner has a nice, modern interface and reminds me of Wise Registry Cleaner (toward the top of this list). Results are separated into sections for easily viewing categories a registry error belongs to.

The scanning speed is decent and then shows what’s called a “Damage Level” so you know how severe the errors may be before fixing them. Registry items are backed up before any corrections are done.

Download Pointstone Registry Cleaner v4.20 for Free

Note: Click the download link below the "Registry Cleaner" column to start the download.

Registry Distiller v1.03.

Registry Distiller is another free registry cleaner, but it doesn’t look as neat as the others in this list. The program’s interface isn’t very easy to work with or view results in. However, with that being said, it apparently does a great job finding errors.

When I tested Registry Distiller, it took 10 seconds to find 500+ errors, which is much better than some of the other registry cleaners in this list.

Registry Fixer v2.0.

Registry Fixer is a free registry cleaner from SS-Tools that is likely one of the easiest programs I’ve ever used. With barely any options, and an open, clean program window, it’s easy to start a scan in seconds.

Only one option is available with Registry Fixer, which is to back up the registry before cleaning. This setting is enabled by default.

Download Registry Fixer v2.0 for Free

Note: Registry Fixer is also available for portable USB drives from the download page.

Registry Life, by ChemTable Software, is a free registry cleaner that runs your through an easy-to-use wizard to clean the registry.

Using Registry Life, you can not only fix registry issues but also defrag the registry and even have quick access to an additional free program (Autorun Organizer) that can stop or delay programs from starting up with your computer.

One thing I didn't like while testing Registry Life is that it tries to install what’s called “Soft Organizer” during the setup process. You'll need to uncheck this option to stop it from installing if you don't want it.

Download Registry Life v3.47 for Free

Registry Recycler is another free registry cleaner that seems to find more registry errors than some of the other programs in this list.

The program automatically creates registry backups before cleaning to ensure you can always return to a working state if anything goes wrong during the process. In addition to cleaning, Registry Recycler can also defrag the registry.

A quick look at the program's version history shows that it's updated pretty frequently, which is great.

TweakNow RegCleaner is another registry cleaner that serves as a suite with many other built-in tools.

The registry cleaner in this program has a regular and deep scanning option to ensure it gets as many errors and problems as it can. You can even open a particular path directly in the Windows Registry Editor to see exactly what you’re looking at.

One thing I didn’t like about this program is that it’s a little confusing to know which registry items you’re going to remove and which will stay intact.

One thing I disliked about this registry cleaner is that the interface is a little difficult to maneuver around in.

Know of Another Free Registry Cleaner?

I've tried to list every freeware registry cleaner available in this list but if I missed one, let me know so I can add it!

Important: I have no intention of including registry cleaners in this list that are not 100% free.

Let me know if one of the freeware registry cleaners above has started charging users so I can remove it from this list
