Registry Usage (Ru)

Registry Usage (Ru) is a lightweight command line utility designed to help you generate reports for specific registry keys. The idea behind the tool is to analyze the impact of the key and provide a report on the total size of the specified registry along with its subkeys. According to the developer, the report can be saved in a CSV format and therefore, be easily imported for further investigation in other third party programs.
The tool can come in handy for the times when you need to check for a particular registry key and make sure that it is present on all machines managed. Generally speaking, to get a registry key usage report you need to have some data collected from the corresponding client to a CM database or simpler, the hardware inventory.
Having a report with the size, can help administrators find out how much data is stored to the database per user and application. Consequently, you can identify resource problems that inevitably lead to performance issues as well as bottlenecks. The direct advantage would be that, based on this information, you can eliminate registry keys that eat up too much resources and therefore, can have an overall negative impact on the performance of the machines.
