37 Free Registry Cleaners

A List of the Best Freeware Registry Cleaner and Registry Repair Software

By

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 uncheck 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 v7.3.0 in Windows 8.

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.

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 installable versions are available.

I tested the installable version of Eusing Free Registry Cleaner v3.5 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.

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.

Cleanersoft Software says that their Free Registry Fix program works on Windows 8, 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 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 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 8, 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 v2.8 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 v2.3.4 in Windows 8 and it seemed to work well, but it's only listed as supporting up to Windows Vista.

16. 360Amigo System Speedup Free

360Amigo System Speedup Free is a good freeware registry cleaner. In addition to registry cleaning, you can also clean out junk files or run a disk defragment, as this program is actually a suite of many different tools.

I found many additional registry fragments that could be cleaned with 360Amigo System Speedup that some other registry cleaners I tested missed. Even though a Pro version is available, I've seen no nag screens or pop-up windows trying to sell it.

360Amigo System Speedup Free works in Windows 8, 7, Vista, and XP.

I tested 360Amigo System Speedup Free v1.2.1.8200 in Windows 8.

Note: The download link I've included here is to CNET's Download.com. 360Amigo does not host a copy of 360Amigo System Speedup Free on their own site.

17. 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.

One thing I don't like is the fact that there aren't any options for automatically backing up the registry before cleaning out the errors. This option is a manual setting that isn't noticed at first.

ACleaner works in Windows 8, 7, Vista, and XP.

I tested ACleaner v4.0 in Windows 8.

18. Secure Eraser

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.

Secure Eraser works with Windows 8, 7, Vista, and XP.

I tested Secure Eraser v4.201 in Windows 8.

19. 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 Argente Registry Cleaner v3.1.0.1 in Windows 8.

Note: The website for Argente Software is in Spanish, but this download link is to an English page.

20. 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.
