Registry scanner

Updated: 04/26/2017 by Computer Hope

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 theory is that this process makes the system run more efficiently since the Registry has been "cleaned" of these useless entries.

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