Top 5 Freeware Registry Cleaners That Improve PC Performance

freeware registry cleanerThe Windows Registry is the root ball of the operating system. Every little bit of system information is rooted in the registry, be it software, drivers, user information or registration data.

Over the lifetime of a computer, numerous tools are installed, updated, moved or removed. Even if done thoroughly, this can create a mess in the registry when files are left behind and references become outdated. As a result, the computer slows down, programs produce registry-related errors, and eventually the system becomes unstable.

There is a number of freeware registry cleaner apps out there that can fix common registry errors, such as missing shared DLLs, incorrect file extensions, invalid paths, missing shortcuts, orphan Active X objects, invalid devices, invalid links to startup programs, and lots more.

Here is a short review of the five best freeware registry cleaners.

5. CCleaner

CCleanerCCleaner definitely is the most popular Windows system optimization tool. It comes with a ton of features, one of them being a freeware registry cleaner.

CCleaner is available for all Windows versions.

If you’re a diligent user, who only installs programs he really needs and who uninstalls programs thoroughly, you won’t need a full-fledged deep registry cleaner. The registry cleaning feature included in CCleaner should be sufficient. And since CCleaner is a tool you should use in the first place, it’s very convenient.

CCleaner can not backup your registry. It’s advisable that you create a manual backup of your registry.

4. Eusing Free Registry Cleaner

free registry cleanerEusing’s Registry Cleaner is a tool dedicated to registry cleaning. It’s perfect for people who cannot be bothered as it is very basic and easy to use.

The tool is compatible with Windows 95 through Windows 7.

This freeware registry cleaner scans a little deeper and finds many invalid entries that were not detected by CCleaner.

Through > File you can access additional features, such as a full registry or a Windows backup. If you run into problems, you can easily restore a previous registry version under > Action or the Tasks option.

3. nCleaner second

nCleaner secondnCleaner comes highly recommended from our IT industry superhero and tech guru Karl, who wrote a thorough nCleaner review last year. Please refer to Karl’s review for in-depth information!

The latest version of this tool is called nCleaner second and it is one of the most comprehensive free system cleaning tools on the market. Like CCleaner, it also features a registry cleaner.

Unfortunately, it is not yet available for Windows 7. Currently, Windows XP, 2003, and Vista are supported.

To clean the registry, go with the > Clean System option and continue with the > Registry clean and repair option. Before you start, you can backup the registry and in case something went wrong, restore it. Right there, you can also create a system restore point, which also backs up your registry.

2. Auslogics Registry Cleaner

auslogics registry cleanerHere we have a very simple to use registry cleaner, which is perfectly suited for the novice user.

Auslogics Registry Cleaner is distributed for Windows 2003 through 7 and supports both 32- and 64-bit.

The cool thing about this cleaner is that it comes with a wizard that guides you through the scan. You can select either a quick or an advanced scan. When running an advanced scan, also critical items, e.g. software and shared DLLs, can be examined. Per default, only safe items are checked and a warning is displayed, if you attempt to scan items that require experience.

The wizard offers a restore changes option. So I was wondering where the option to backup the registry was hidden. Per default, registry keys are backed up before you fix problems. However, you can deselect this option.

Finally, the tool displays the speed the computer supposedly gained after the cleaning process. Before you close the application, you can also view the full report.

1. Wise Registry Cleaner

Wise Registry CleanerWise Registry Cleaner is one of the most comprehensive cleaners in this list. Hence, it made it to the number 1 position.

Despite many options, the interface remains clear. Even the novice user will find this tool easy to use, since the program guides the user through each step upon running it for the first time.

Wise Registry Cleaner is available for Windows 98 through 7 and supports 32- and 64-bit.

While the tool may ask you for your eMail address and offer to download further software during installation, it’s all optional. Just be sure to uncheck the respective boxes.

When you run Wise Registry Cleaner for the first time, you are greeted with a window that provides a link to a quick start guide. The next notice offers to perform an automatic registry backup. You can choose to never see these windows again. And don’t worry, you can manually launch a full registry backup or restore a previous registry version anytime. Also the guide and further material is available through > Help.

Once you got through the initial welcome procedure, you are pointed to the start button. Entries are categorized as safe or not fully safe to fix. Using the respective buttons you can check the safe entries, all, none or invert all checks. All these options make the tool look complicated, but I find them quite convenient.

Through > Options you can edit settings and create a scheduled task to launch and auto run the tool.

    If the speed of your computer is slackened greatly or even crashes while running, you may need a tool called uFlysoft Registry Cleaner to clean the junk files as well as to optimize your system.

    I like this post .but according to me there are several free registry cleaners available for Windows, but very few you may trust enough to clean your Windows Registry. I am using TunePRO360 Registry Cleaner. TunePRO360 Registry Cleaner is one such registry cleaner and repair tool, I just came across, that you may want to check out

    I agree with the Ccleaner utility as it had successfully clean the corrupt registry. But last week I tried one more utility Ninja TuneUp which had also worked successfully to clean away the crap files.

    Most of these supposed ‘geeks’ that say ‘registry cleaners are snake oil’ are idiots who have done very little programming, if at all, so they hardly understand what the registry is or how important it is to keep it trimmed of unnecessary entries. Claiming that it doesn’t need regular maintenance is a bit like saying that your browser will continue to perform fine over time as it collects thousands of unnecessary cookies. Add to this the fact that Windows itself has gotten larger, more unstable and buggier over the years, and you have a playground for performance sapping, spaghetti code.
    The registry is rarely described as the main compendium of software and hardware assets and info, a scratch pad for Windows and other programs, and a hell of a large file before it gets peppered with thousands of new pieces of data, hidden or not, encrypted or not, well beyond the huge number of useless entries of the ‘default’ type. I’ve been installing software for many years on every version since 98, back when Microsoft admitted that this was an issue by putting out their own cleaning utility, which they eventually stopped updating. Why should they continue to focus on functions that are better performed by third part apps, and besides, weren’t they just admitting that their amazing Windows product was bloated crap? After all, I’ve seen Windows stumble over itself doubly so when dealing with Microsoft’s own programs such as Office to a greater extent than third party software from much smaller groups of coders. Besides, it would have been better in the long run if Microsoft had re-written rather than ‘ungraded’ the general structure of Windows (even though that would have caused more compatibility issues) instead of simply ‘patching’ in sub-systems. Microsoft is mainly a marketing dynamo, not a hive of genius programmers.
    I’m not saying that everyone needs a registry cleaner or that all registry cleaners are alike. Certainly some registry cleaners miss a lot of what I would consider important entries, and some include more features than necessary, but no computer that I’ve had to work on that was riddled with performance issues had an active registry cleaner, or any other kind of cleaner for that matter, doing important ‘preventive maintenance cleaning’, ‘house keeping chores’ or whatever you want to call it, of useless files and registry entries. The need for such a program is directly related to the amount you use your computer, even if all you do is type letters, peruse the Internet and play multimedia.
    A closely related issue is the use of uninstallers that attempt to clean up after a program is removed. Although I agree with the use of these also, there needs to be more care taken in this case since they are more likely to remove too much. Neither area of software tools has been well tested and documented, so caution is advised.

    Personally I like Ninja TuneUp – it creates a backup of removed registry items and lets you delete old restore points, i never had any issue with it.
