Windows Registry is one of the most crucial components of Windows as it stores all the information about the PC in one place, such as system settings, programs installed and uninstalled, hardware installed, and more. When we uninstall an application from the system, the information related to this action gets stored in the Windows Registry. But, this information is of no use to the system or us after deleting the program.

Therefore, removing redundant information like this from Windows Registry is always better before it starts affecting the system's performance. In that case, registry cleaner tools come into use and help us delete all the useless files with ease. In this article, we've shared the five best registry cleaners for PC. Let's choose the best registry cleaner tool for your Windows PC.

What Is Registry Cleaner?

Registry Cleaner is third-party software that finds redundant registry keys and values within the directory and lets us delete them. These tools search for invalid entries, missing file references, and broken registry keys and links in Windows Registry and take necessary actions against them.

One of the primary functions of a registry cleaning tool is to improve the system's performance by deleting useless registry data. In short, they assist you in removing inconsistencies from the system caused by making changes in the settings or installing and uninstalling programs.
