Registry scanner

Updated: 11/16/2019 by Computer Hope

Registry scanner, registry cleaner, and registry checker may refer to any of the following:

1. A registry scanner or registry cleaner is third-party software for Microsoft Windows that searches for registry entries that are redundant or no longer used, and removes or resolves them. The purpose is to make the system run more efficiently by "cleaning" it of these useless registry entries.


The usefulness of registry scanners is debatable; users should be careful when installing them as they are a common source of malware.

2. The Registry Checker is also a tool included with early versions of the Windows System Information tool for checking the registry.
