Registry Usage (RU) is a command-line utility that reports the registry space usage for the registry key you specify. By default it recurses subkeys to show the total size of a key and its subkeys.
From Major Geeks review:
The generated report can by saved as CSV file with these fields:Having access to this data can help run down issues and be especially useful for admins managing multiple machines to verify stored data size per user and application.
Gleaning this information will simplify eliminating keys that are using too much of the machine's resources. Resource hogs can potentially hinder performance.
