Maintaining the computer is a hard task to do because of the abundance of factors you need to consider in keeping it at peak performance. One of the most overlooked parts is the registry especially for those without much knowledge about PCs. For those who use Windows as their operating system, this part of the computer keeps important data about the currently installed applications. It also stores your preferences and maintains the settings you keep for every application. If this experiences issues, you may experience slower performance and less system stability. If the user is prone to installing and uninstalling applications, the registry may start having a lot of issues.


How does this happen?

Most of the time, files called malware which includes viruses, spyware, and adware can do changes in the registry that can cause it to have issues. Once it does something to this, you may expect frequent error messages along with slow performance. As mentioned, it also happens if you are prone to installing and uninstalling applications. If you are encountering these issues then don't worry as we list the top 4 registry cleaners here, as well as have a listing of the best registry cleaners in our review section.


What are registry cleaners?

Registry cleaners are applications which you can use to manage this part of the computer. Although users can manually fix errors that they may find here, the values here are very sensitive and may cause some applications to crash if configured wrongly. With registry cleaners, users can simply click a couple of buttons to do this job automatically. Aside from this, these applications also come with multiple features such as file cleanup and privacy safety as to give holistic performance improvement for your computer.

Here in ReviewFyer, we have reviewed most of the popular choices for registry cleaners and analyzed which ones are best for overall user experience and for providing better performance for your Windows 10 computer.


Launched in 2018, Restoro has always been a popular choice for improving the overall performance of the computer. The application is equipped with a holistic set of features which vary in usage from excess file cleaning, corrupted file repairing, and registry optimizing. Given the abundance of its features, users can expect a faster performance once the application is used. Even though registry optimizing is only a single tool out of many, the application takes the top spot on our list because it is the most effective and fastest in doing its job.

Upon testing, we discovered that the application uses all of its tools step-by-step, making sure to fix every issue found in any particular part such as the registry, the system files, and more. Although there was no exact number of issues that it has found reported to us, we still had a massive increase in performance and less system issues when we tested the application. Given that the registry is closely related to the stability of the applications that are currently explored, it is important to constantly maintain it which was easy to do with Restoro.

RegClean Pro

RegClean Pro is an application created by Systweak which is based in India. It is also a popular choice because of its integrated registry defrag tool that was able to optimize our test computer properly. With this application, users can select the particular parts of the registry which they want to fix. This helps in ensuring that crucial parts which user do no want to risk will not be configured by the application. You can also save specific registry settings. However, the interface may be a bit complicated especially for those without much knowledge of the registry because of the lack of guides.

Aside from this, the application also has a startup optimizer which can help you minimize the number of applications that open alongside the computer. This is because without your knowledge, some applications automatically program itself to open alongside the computer, making startups slower. This is because it takes much of your computer’s resources, often causing screen freezing and lagging during startup. With the startup optimizer feature, you can prioritize only those that you will instantly need upon startup. This is especially helpful for Windows 10 computers which has a lot of complaints about its slow startup times.

Advanced SystemCare PRO

Advanced SystemCare PRO promises to improve computer performance by about 300%. Although its actual results were not close to what it promised upon testing, it still manages to take a higher spot in our list because of the abundance of features it provides and the effectiveness of these. It is a helpful system optimizer with its complete set of tools which target different parts of the PC, which is alike with our top pick, Restoro. It also has a very simple interface which users can instantly get familiar with. Lastly, they also have affordable pricing plans which makes them a good choice for those on a budget.

As mentioned above, Iobit’s Advanced SystemCare PRO didn’t live up to its promised speed. However, it was still able to fix a majority of our registry’s issues and improved the performance of the computer. As a registry optimizer, it is in the middle in terms of actual quality. As an overall system optimizer, though, the application does not disappoint. It also has a free version where users can try some of its features to see if they should buy a Pro version.

Registry Reviver

Registry Reviver is a cleaner for those looking for a straightforward application that is effective in its job of fixing registry issues. Upon testing, we discovered that it was able to optimize about 5000 entries in the registry which helped in stabilizing the system. Aside from this, the application also uses an effective scanner which was able to sort out the different issues faced by our registry. All of this comes in a very simple interface where information such as the number of issues found along with its severity can be seen. The application can instantly start a scan of the computer, providing users with information about their hardware. Next, it will display the different issues of the registry for the user to be aware of what causes their computer to be slower. Finally, it will fix these.

Aside from this, though, it falls short on the number of features. This is mainly because the only other features offered by the application is the startup manager which can make your computer startups faster along with a registry cleaning scheduler. Still, it takes a higher spot in our list because of its effectiveness in fixing the problems of the registry.

Final thoughts on the top registry cleaner.

In choosing for the best registry cleaner for your computer, you must think about its specific needs. If you’re looking for a straightforward application which only specializes in registry cleaning, you may prefer Registry Reviver or RegClean Pro. If you want to have a holistic repair for your computer to improve its performance beyond the registry, Restoro and Advanced SystemCare PRO are recommended for you.
