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.
Important: Free registry cleaners should only be used to troubleshoot specific issues.
1 . CCleaner
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.
CCleaner provides both install able 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 CCleaner freeware registry cleaner tool.
The CCleaner registry cleaner work on Windows 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.
I tested CCleaner using both their portable and installable versions on a 64-bit version of Windows 8.1.
2 . Wise Registry Cleaner
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 comes in both installable and portable versions and can be used on Windows 8, 7, Vista, and XP. 64-bit Windows versions are supported.
I tested the installable version of Wise Registry Cleaner v8.26 in Windows 8.
Note: I’ve linked to the download page for all of Wise Cleaner’s products so scroll down until you find Wise Registry Cleaner.
3 . JetClean
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!
The JetClean registry cleaner supports both 32-bit and 64-bit versions of Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.
I tested JetClean v1.5.0 in Windows 7.
4 . Auslogics Registry Cleaner
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 is compatible with 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 v4.1 in Windows 7.
Note: Before downloading Auslogics Registry Cleaner, you may be asked to download other programs, but it’s easy to deselect them if you wish not to install them.
5 . AML Registry Cleaner
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 ofnot accidentally causing more problems.
AML Registry Cleaner works on both 64-bit and 32-bit versions of Windows 8, 7, Vista, and XP, as well as on some Windows Server operating systems.
I tested AML Registry Cleaner v4.25 in Windows 7.
6 . Registry Repair
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 works in Windows 8, 7, Vista, XP, Server 2003, and older Windows operating systems like Windows 2000, NT, ME and 98.
I tested Glarysoft’s Registry Repair in Windows 7.
Note: After the installation of Registry Repair, you’re asked if you’d like to run the program (this is typical) but you may also be asked if you’d like to install other programs from Glarysoft. Be sure to uncheck them if you’re not interested. More »
7 . SlimCleaner Free
I was pretty impressed with SlimCleaner Free. Aside from a standard registry cleaning abilities, there are lots of completely free extras with this program like software update checks, startup optimization, system cleaning, and a lot more.
SlimCleaner Free works in Windows 8, 7, Vista, and XP, and 2000.
I tested SlimCleaner Free v4.0 in Windows 7.
8 . PowerTools Lite
PowerTools Lite 2013 is a freeware registry cleaner created by Macecraft, makers of several popular Windows utilities. PowerTools Lite was fast and found a similar number of needless registry entries as other tools in this area of my list.
PowerTools Lite works with Windows 8, 7, Vista, and XP.
I tested PowerTools Lite in Windows 7. No toolbars or other programs tried to install like with some other free registry cleaners.
9 . Kingsoft PC Doctor
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 did not 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 is said to work with Windows 7, Vista, and XP.
I tested Kingsoft PC Doctor in Windows 8 without any issues.
10 . EasyCleaner
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!
The ToniArts website says that EasyCleaner works in Windows 7, Vista, XP, 2000, NT, ME, 98, and 95. Both installer and portable versions of this registry cleaner are available.
I tested the installable version of EasyCleaner v220.127.116.110 in Windows 7.
11 . Advanced SystemCare Free
Advanced SystemCare Free is one of IObit’s many freeware programs. “Registry Fix” is the utility in Advanced SystemCare that does the registry cleaning.
I find the registry scan to be very quick regardless of the amount 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 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 un-check all the other options. All the features that are offered can be overwhelming and get in your way.
Advanced SystemCare Free works in Windows 8, 7, Vista, and XP.
I tested Advanced SystemCare Free v8.0 in Windows 7.
12 . Eusing Free Registry Cleaner
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.
Eusing Software says that their free registry cleaner works on Windows 8, 7, Vista, Server 2003, XP, 2000, NT, ME, 98, and 95. Portable and install-able versions are available.
I tested the installable version of Eusing Free Registry Cleaner v3.5 in Windows 7.
13 . Cleanersoft Free Registry Fix
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.
Cleanersoft Software says that their Free Registry Fix program works on Windows 8, 7, Vista, Server 2003, XP, 2000, NT, ME, 98, and 95.
I tested Cleanersoft Free Registry Fix v2.1 on Windows XP and didn’t have any problems.
14 . Free Window Registry Repair
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.
RegSofts Software’s website says Free Window Registry Repair is compatible with Windows 8, 7, Vista, XP, and 2000, NT, ME and 98.
I tested Free Window Registry Repair v3.0 in Windows 7.
15 . nCleaner
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 in Windows 8 and it seemed to work well, but it’s only listed as supporting up to Windows Vista.
16 . ACleaner
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.
ACleaner works in Windows 8, 7, Vista, and XP. I tested v4.1 in Windows 8 and didn’t find any problems.
17 . Secure Eraser
Secure Eraser is a program suite that includes a dedicated section for registry cleaning.
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.
Secure Eraser works with Windows 8, 7, Vista, and XP. I tested version 4.201 in Windows 8.
18 . Argente Registry Cleaner
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.
One thing I didn’t much care for in this registry cleaner was that I couldn’t find an option to back up the registry keys in case the cleanup didn’t work as expected.
Argente Registry Cleaner works in Windows 8, 7, Vista, and XP. I tested version 18.104.22.168 in Windows 8.
Note: The website for Argente Software is in Spanish, but this download link is to an English page.
19 . Ashampoo WinOptimizer Free
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 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.
Ashampoo WinOptimizer Free works in Windows 7, Vista, and XP. I tested Ashampoo WinOptimizer v1.0.0 in Windows 8 without any issues.
20 . Free Error Cleaner
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 in Windows 8 without any issues.
21 . Pointstone Registry Cleaner
Pointstone Registry Cleaner has a nice, modern interface and reminds me of Wise Registry Cleaner. 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.
Pointstone Registry Cleaner works in Windows 8, 7, Vista, and XP. I tested v4.20 in Windows 7 without any problems.
Note: Click the download link below the “Registry Cleaner” column to start the download.
22 . Registry Distiller
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 Distiller is said to work in Windows Vista and XP. I tested Registry Distiller version 1.03 in Windows 8 and didn’t have any issues.
23 . Registry Fixer
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.
Registry Fixer is said to work with Windows XP only, though I tested version 2.0 in Windows 8 without any problems.
Note: Registry Fixer is also available for portable USB drives from the download link.
24 . Registry Life
Registry Life, by ChemTable Software, is a free registry cleaner that starts a scan the moment you open the program, taking you through an easy-to-use wizard to clean the registry. You can fix registry issues and even defrag the registry with Registry Life.
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 choose a custom install and un-check this option to stop it from installing.
Registry Life is said to work with 32-bit and 64-bit versions of Windows 8, 7, Vista, and XP. I tested in Windows 7 and didn’t encounter any troubles.
Note: During setup, Registry Life asks to install a toolbar. You must choose a custom installation and opt out if you don’t want the extra software.
25 . Registry Recycler
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.
Registry Recycler works with Windows 8, 7, Vista, and XP. I tested version 0.9.2.8 in Windows 8.
Note: Registry Recycler can be downloaded as either a regular installer or a portable one, both of which are found at the download page.
26 . RegSeeker
RegSeeker is another free registry cleaner that’s available for both regular and portable installs. Scanning is quick and seems to find a reasonable amount of the same errors the other programs in this list can find.
The interface of this program isn’t quite as friendly as some of these other registry cleaners, but it seems to function in a similar fashion, finding and removing most of the same registry issues.
RegSeeker works with Windows 8, 7, Vista, and XP. I tested RegSeeker v2.57 in Windows 8.
27 . TweakNow RegCleaner
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.
TweakNow RegCleaner works with Windows 8, 7, Vista, and XP. I tested TweakNow RegCleaner in Windows 8.
28 . Vit Registry Fix
Vit Registry Fix is an easy-to-use registry cleaner with a simple interface. The “Scan” and “Fix Error” buttons are really easy to see so there’s no confusion in what you’re doing. There’s also a dedicated rescue center to restore the registry if you have accidentally removed items you wanted to keep.
Overall, this program looks to work quite well and is comparable to the others in this list.
Vit Registry Fix works with Windows 8, 7, Vista, and XP. I tested Vit Registry Fix in Windows 8.
Note: To avoid downloading a trial of the Professional version, look to the bottom right of the download page to find a link called “Download Vit Registry Fix: Free Edition” in the Extras section.
29 . Mr. Fix
Mr. Fix is another good registry cleaner that seems to find similar issues as the other programs in this list.
This program asks you to back up the registry before you actually remove any problems, which is a nice feature. You can then easily restore the registry if something goes wrong.
Mr. Fix is said to work with Windows Vista and XP. I tested Mr. Fix in Windows 7 without any issues.
Note: When you install Mr. Fix, be sure to decline any additional programs you don’t want the installer to add to Windows.
30 . MV RegClean
MV RegClean looks very outdated, any may very well be, but it seems to do well with deep registry cleaning.
While testing this program, it seemingly found many more problems than most of the other programs in this list. The registry is automatically backed up, so there’s no need to do it manually.
One thing I disliked about this registry cleaner is that the interface is a little difficult to maneuver around in.
MV RegClean is said to work in Windows Vista and XP. I tested MV RegClean in Windows 8 without any issues.
31 . Baidu PC Faster
Baidu PC faster is a program suite that contains tons of system optimization tools, one of which is a registry cleaner. The program installs and works fast, and has a friendly interface to it.
It’s great that Baidu PC Faster automatically backs up the registry before modifying it, but you unfortunately must scan and clean for Windows junk files at the same time you’re cleaning registry issues.
You can find the registry cleaner portion of Baidu PC Faster in the Cleaner menu.
I tested Baidu PC Faster in Windows 8 and Windows 7 without any issues. It should also works in Windows Vista and XP.
32 . RegCleaner
RegCleaner seems to find similar errors and issues in the registry as some of the other programs from this list.
A glaring issue with this program is that the controls for scanning and removing registry errors are in the file menu. This is much different than the other programs in this list because it makes controlling the program a bit complex.
Aside from the interface, RegCleaner finds registry errors as it says it will.
RegCleaner is said to work in Windows 7, Vista, and XP. I tested version 22.214.171.1240 in Windows 8 and didn’t find any issues.
33 . Your Cleaner
Your Cleaner is a nice registry cleaner with an easy-to-use interface.
While testing this program, it found a good amount of errors, making it comparable to most of the other programs in this list. Also, the registry is automatically backed up before any cleaning is performed, which is a nice feature.
Your Cleaner is said to work with Windows 7, Vista, and XP. I tested Your Cleaner v1.11 in Windows 8 and it worked fine.
Note: The default language for the program installer may be Estonian, but you can easily change it from the dropdown box. Also, the download is a RAR FILE , meaning you’ll need a program like 7-ZIP to open it.
34 . FCleaner
FCleaner is a registry cleaner from FTweak that’s coupled with many other tools, similar to CCleaner. The user interface is a bit strange, but all the proper functions are there with a nice version available to use on a portable USB device.
I discovered FCleaner did not seem to find nearly as many errors and other issues with the registry as the other cleaners in this list, so it’s ranked accordingly.
FCleaner is said to work in Windows 7, Vista, and XP. I tested FCleaner in Windows 8 without any problems.
Note: Download the regular installer file under the section titled “FCleaner Latest Stable Version,” whereas the portable version is found in the section just following it.
35 . Dedaulus System Cleaner
Dedaulus System Cleaner is another program suite, with a section just for cleaning registry errors.
While testing this program, it seemed to find a good amount of errors and even asked to backup the registry before removing the errors.
Dedaulus Registry Cleaner is said to work with Windows Vista and XP. I tested v1.6 in Windows 8 without any issues.
Note: The program installer is actually a compressed EXE file. Use a decompressor like WinZip to extract the program into a folder. It can then be used normally or treated as a portable install.
