The registry stores information that is necessary to configure the operating system for users, applications and hardware devices. As the user uninstalls programs, the registry accumulates much data which is no longer associated with files, settings and applications. This data is redundant and can cause errors and loss of system performance. To avoid these consequences, it is recommended to clean the registry on a regular basis.

Editing the registry is one of the main functions of Reg Organizer. The program offers a feature-rich editor that can be used to clone registry keys, view information on any key, export or import a specific key or part of the registry to file, search and bookmark keys as Favorites. All these operations are intended for advanced users who know the registry well.
