A List of the Best Freeware Registry Cleaner and Registry Repair Software
By Tim Fisher, About.com Guide
Updated January 2013
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, NOT as part of your regular PC maintenance. See my Registry Cleaner FAQ for more about registry cleaning and registry cleaner software.
1. CCleaner
CCleaner
 is the best free registry cleaner program I've tested. It's easy to 
use, prompts you backup the registry before it makes changes, and 
includes a number of other useful tools.
The CCleaner registry 
cleaner work on Windows 8, 7, Vista, XP, Server 2008/2003, and older 
Windows versions like 2000, NT, ME and 98. 64-bit Windows versions are 
also supported.
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.
I tested CCleaner v3.26.1888 using both their portable and installable versions on a 64-bit version of Windows 7.
2. 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.
The
 JetClean registry cleaner supports both 32-bit and 64-bit versions of 
Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.
JetClean
 scanned the entire registry in just a few seconds, has a well designed 
interface, and didn't try to push some unnecessary browser toolbar on me
 during installation.
There were twp things I didn't like about 
JetClean. One: It isn't available in a portable version. Two: The number
 of cookies that JetClean considers keepable, by default, is a bit 
excessive.
I tested JetClean v1.4.0 in Windows 7.3. Wise Registry Cleaner
Wise
 Registry Cleaner comes in very close to the other top rated registry 
fix tools. ZhiQing Soft has put together a fantastic free registry 
cleaner program.
Wise Registry Cleaner comes in both installable 
and portable versions and can be used on Windows 7, all the way back 
through Windows 98. 64-bit Windows versions are supported.
Some 
big pluses for Wise's free registry cleaner include fast registry scans 
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 during 
installation but it's easy to skip.
I tested the installable version of Wise Registry Cleaner v7.31.469 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.
Auslogics Registry Cleaner is compatible with 
Windows 7, Server 2008 & 2003, Vista, XP, and 2000. Both 32-bit and 
64-bit versions of Windows are supported.
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 two higher rated registry repair tools 
in my list don't give you the results you were looking for, give 
Auslogics Registry Cleaner a try.
I tested Auslogics Registry Cleaner v2.3.0.5 in Windows 7.
Note:
 During installation, Auslogics Registry Cleaner tries to install a 
browser toolbar and make changes to your browser's home page and new 
tabs page. Be sure to uncheck those options if you're not interested.
5. Advanced SystemCare Free
Advanced
 SystemCare Free from IObit is another excellent free registry cleaner 
program. Advanced SystemCare Free is very easy to use, has an excellent 
interface, and includes several other "system care" capabilities, 
including the ability to remove some malware, clean junk files, and 
more.
Advanced SystemCare Free works in Windows 8, 7, Vista, XP, 
and 2000. According to IObit, both 32-bit and 64-bit versions of Windows
 are supported.
I tested the registry fixing abilities of Advanced SystemCare Free v5.3.0.246 in Windows 7.
Note: Advanced SystemCare Free tries to install a custom browser toolbar during its setup but it's easy to decline if you so choose.
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 7, Vista, XP, Server 2003, and older Windows operating systems 
like Windows 2000, NT, ME and 98.
I tested Glarysoft's Registry Repair v4.1.0.388 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're also asked if you'd like
 to set "Glary Search" as your browser's homepage. Be sure to uncheck 
that if you're not interested.
7. 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.
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.
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!
I tested the installable version of EasyCleaner v2.0.6.380 in Windows 7.
8. Comodo System Utilities
Comodo
 System Utilities is yet another good freeware registry cleaner program.
 It's simple to use and scanned the registry in a reasonable amount of 
time.
The Comodo System Utilities tool is designed for Windows 7,
 Vista, Server 2003, and XP. It works on both 32-bit and 64-bit versions
 of Windows.
I tested Comodo System Utilities v4.0.226743.26 in 
Windows 7. There are several other features in this "utility" but I only
 looked at the registry cleaning portion.
I'm usually a big fan 
of Comodo products and Comodo System Utilities delivered on my 
exceptions. I especially liked a seemingly tiny feature: the ability to 
automatically create a restore point prior to clearing the registry. 
That could really come in handy if you run into a problem post-cleaning.
9. 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.
Eusing Software 
says that their free registry cleaner works on Windows 7, Vista, Server 
2003, XP, 2000, NT, ME, 98, and 95. Portable and installable versions 
are available.
I tested the installable version of Eusing Free Registry Cleaner v2.8.1 in Windows 7.
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.
10. 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.
Cleanersoft Software says that their 
Free Registry Fix program works on Windows 7, Vista, Server 2003, XP, 
2000, NT, ME, 98, and 95.
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.
I tested Cleanersoft Free Registry Fix v1.8 on Windows 7 and didn't have any problems.
11. Free Window Registry Repair
Free
 Window Registry Repair reminds me a lot of Eusing Free Registry Cleaner
 and Cleanersoft Free Registry Fix and so my assessment is similar. Try 
this registry cleaner if you need to, skip it and try a better one if you don't.
RegSofts Software's website says Free Window Registry Repair is compatible with Windows 7, Vista, XP, and 2000, NT, ME and 98.
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.
I tested Free Window Registry Repair in Windows 7.
12. Little Registry Cleaner
Little
 Registry Cleaner seems to be as good a registry cleaner as any other in
 this area of my list. I do like that it's an open source program.
Little
 Registry Cleaner is an open source registry cleaner that works on 
Windows 7, Vista, XP, and 2000 - on both 32-bit and 64-bit versions. 
Installable and portable versions are available.
One particular high point? As soon as the installation begins, Little Registry Cleaner says this: "This program is freeware. If you paid for a copy o this program, get a refund!" That's pretty clear: this is a completely free registry cleaner.
Note:
 During installation, you're prompted to agree to install a browser 
toolbar, an ASPCA add-on, and to change your default browser search 
provider and homepage to another. Just uncheck those options and decline
 the toolbar and add-on installations.
I last tested the installable version of Little Registry Cleaner v1.4.2 in Windows 7.
Update:
 As of Little Registry Cleaner v1.5.1, the program does not work due to 
an issue reading the latest version of .NET Framework 4.0. This is 
probably an easy fix and may be corrected in a future update but for 
now, since it won't start, I can't recommend this registry cleaner.
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 will not, under any circumstances, include registry cleaners in this list that are not 100% free. In other words, I will only include freeware registry cleaners - NO shareware and NO trialware registry cleaners.
