10 Best Free Registry Cleaner Software and Tools as of 2020

Are you experiencing a slowed-down performance of your PC or laptop? Do you have a not so powerful computer from a few years back or one running on older versions of Windows? Then PC optimization software such as Registry Cleaner Software should be one of your options to take care of this issue.

You might already have the Windows Disk Cleanup tool in your OS, but it is less effective than most cleaner apps. A typical registry cleaner program can do many more functions. For example, remove temporary Internet files, browser cache, and history, junk files, log files, etc. Essentially, it is a third-party application designed to remove redundant and obsolete files from the Windows registry.

Most of the registry cleaners have the same functionality, more or less: they scan, clean, and fix. Some perform faster, and others bet on thorough cleaning. In terms of pricing, it may seem strange, but these utilities aren’t the essential software to use. So, it would be senseless to pay a lot for it. On the other hand, low price usually means poor quality; we all know that.
