What is Registry cleaner? How to use it?

If you figured out that you got some issues with your Windows registry, which requires a registry cleaner to fix it, you have come to the right place. 

The subsequent sections have it all covered whether you want to know about the top recommendations for registry cleaners or the nitty-gritty of this Windows utility. So without further ado, let’s jump into it right away.

What Does a Registry Cleaner Do?

A registry cleaner is a third-party tool explicitly designed and developed for Windows OS. It scans the Windows Registry for broken and redundant entries and removes them. There are a number of reasons that can damage and corrupt your registry keys giving rise to intricate errors like BSOD and more. 

Even when you install, uninstall and modify a program, it tends to leave some remnants back in the system that clutters the system and later causes issues. 

Manufacturers of Registry cleaners claim that using these utilities can speed up your PC, resulting in enhanced performance. However, that is more of a marketing gimmick to get more sales on their products. Registry cleaners certainly work but not to an extent claimed by the vendors or the ads you see on the internet.
