Best registry cleanup freeware

AML Registry Cleaner wasn't part of this list when we first put it together, which was an obvious oversight on our part. It's 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. We tested v4. PowerTools Lite 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 this list. No toolbars or other programs tried to install like with some other free registry cleaners.

However, the tool isn't supported above Windows 7. We tested jv16 PowerTools Lite in Windows 8. Kingsoft PC Doctor is another registry cleaner embedded in a software suite.

While this is the case, the manual scans do find a hefty amount of errors that are just a click away from being removed. 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 the registry, but it did a fine job overall.

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.

We tested v3. There's also a portable version of Argente Registry Cleaner on Softpedia. This free Windows Registry cleaner program packs some great features into a minimal program. For starters, Little Registry Cleaner found a lot more problems in the registry than most other registry cleaners, so if one of the others in this list isn't working well for you, try this one. This program also lets you choose which folder on your computer to use for automatic registry backups before cleaning, can ignore certain files and folders from being scanned, will create a restore point before deleting the registry files, and can scan your computer for invalid registry entries on a schedule.

Little Registry Cleaner should work fine with any recent version of Windows. We tested version 1. Eusing Free Registry Cleaner is another free registry cleaner.

We frequently see references to this particular registry cleaner on other "top" lists, but we didn't find anything spectacular about it. Remember, a registry cleaner program is not a regular PC maintenance tool.

However, we felt compelled to at least include it here after receiving so many suggestions to add it to the list.

We tested the nCleaner v2. 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.

ACleaner works with Windows 10 down through Windows We tested v5 in both Windows 10 and Windows 7 and didn't find any problems.

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. It works with Windows 11, 10, 8, 7, Vista, and XP.

We tested version 5 in Windows 8. 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. 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. However, with that being said, it apparently does a great job finding errors.

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

We were also able to make it work in Windows 10, but the startup optimizer didn't always function as advertised. System Mechanic is another program that can clean up invalid and unused registry entries.

The program is quite a bit more advanced than just a registry cleaner, though. Included in System Mechanic is a variety of tools like an internet browser junk cleaner, Windows junk cleaner, uninstaller tool, file shredder, system performance booster, and more.
