Registry Cleaner

Registry Cleaner:  A registry cleaner is a third-party software utility designed for Microsoft Windows operating system, whose purpose is to remove redundant items from the Windows registry.  Registry cleaners are not supported by Microsoft, but vendors of registry cleaners claim that they are useful to repair inconsistencies arising from manual changes to applications, especially COM-based programs.

We normally do not recommend people do registry cleaners, as malware and scareware are often associated with utilities of this type.

We recommend, CCleaner.  There is a free trial version available, here.
