A registry repair software is sometimes the best solution to a slow and buggy computer. If your PC is cluttered and the Windows registry is broken and disorganized, you will feel the consequences in the performance of your device and it will affect you as a user.

The Windows registry can be looked at as a huge archive that stores all the settings in your computer, such as operating system settings, program settings, hardware settings, etc. Over time, as we continue to install and uninstall programs on the PC, the registry becomes cluttered. Some entries are left behind even after you uninstall a program, spaces form within the registry and the installed programs can begin to open slower than usual. You might also get weird errors and messages. All these are signs that the Windows registry needs to be cleaned, repaired and optimized.

What does a registry cleaner app do to improve the performance of your PC?

The registry cleaners you can find online are developed by third-parties, because Microsoft doesn’t provide such a program for Windows users. Some of these programs focus exclusively on cleaning the Windows registry, while others offer this tool as part of a more complex PC optimizing kit, next to other useful features such as a disk defrag, malware removal, startup optimizer and more.

Registry cleaners work by scanning the Windows registry in order to identify all the registry entries that are broken, corrupt, outdated. There are many types of files that a registry cleaner can delete, such as: file extensions, Windows services, installers, app paths, libraries, DLLs and many others.

Registry cleaners only remove the files that are no longer useful and even so, they don’t take any action without asking for your approval first, before deleting anything.

What are the best registry cleaners to buy in 2020?

Before we give you a list with our top registry cleaning apps of 2020, we also want to give you a piece of advice. No matter what kind of registry cleaning app you want to use, make sure you first do your homework. You should only go with a software that comes from a reputable provider, one that has good customer ratings and reviews.

Another aspect to have in mind is where you download the software from. You should only download it from the official website or a 100% secure source. The internet is full of scamming websites that hide malware in the installer file and when you download the installer, you also download the virus and risk infecting your PC.


One of the best registry cleaning apps on the market and the number 1 in our lineup is RegClean. RegClean was developed by Systweak, an experienced software developer that’s been around since 1999.

This software is compatible with Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10.

RegClean has two versions to offer: a free one and a paid one, called RegClean Pro.

If you are not convinced about purchasing the software, you can start by downloading the free version to test its interface and see what it has to offer. The free version allows you to run full system scans, to identify the issues in your computer. Moreover, the free RegClean allows you to also fix up to 15 registry entries.

If you want to repair all the registry problems found during the scan, you have to upgrade to RegClean Pro.  A license for 1 year is priced at $43 and Systweak throws in a bonus as well. You get a lifetime license for a photo editing software called PhotoStudio v2.1.  (PhotoStudio can be used for capturing images from any devices, to add visual effects to images, create slideshows and presentations and more).

What does RegClean Pro have to offer?

RegClean improves the performance of your PC through several actions it takes:

  • It defrags and optimizes the registry
  • It improves system response time
  • It prevents system crashes and blue screens of death (BSOD)
  • It can run custom scans
  • It creates a full registry backup

Advanced SystemCare Pro

Advanced SystemCare Pro is more than just a registry cleaner. It is a complex utility app developed by IObit. The software is compatible with all the Windows versions from XP to Windows 10. Advanced SystemCare Pro is the number 2 option in our lineup.

The software has reached version number 13.

Just like RegClean, this app also offers a free version and it is also limited in terms of features. The free version offers basic PC cleaning and optimization. It also monitors your PC’s condition in real-time and offers basic protection by removing spyware and infections.

Advanced SystemCare Pro on the other hand, which is the paid version of the app, gives you access to the entire set of features. Here’s what the app has to offer:

  • It offers premium cleaning and optimization of your system
  • Deep registry cleaning
  • Hard disk defragmentation
  • Auto RAM clean feature
  • Auto updates so that you can always benefit from the latest version
  • Full protection by identifying and removing deep system infections
  • Premium surfing protection
  • Tracking data removal
  • Free 24/7 technical support and more

Advanced SystemCare Pro increases the startup time of your PC with up to 200% and your internet speed with up to 300%.

Registry Reviver

Registry Reviver is the 3rd registry cleaning app in our lineup. The software was developed by ReviverSoft, a company that was founded in 2009.

Registry Reviver is compatible with all the Windows versions from XP and above, up to Windows 8. Unfortunately, it doesn’t support Windows 10.

Registry Reviver has a free and a paid version. The free version is quite useful. It allows you to run full scans and solve up to 25 errors. If you want to be able to fix all the registry issues in your system though, you have to upgrade to the paid version that will cost you approximately $30.

What does Registry Reviver have to offer?

Registry Reviver scans your registry, fixes any issues and maintains and optimizes the Windows registry.

Just like the other two apps, Registry Reviver can also reduce the startup time of your computer, by limiting the number of programs that are allowed to launch at Windows startup.

Registry Reviver also reduces to a minimum the number of computer crashes.

The software creates automatic backups and system restore points, just to make sure your data is kept safe.
