DuReg is a command-line tool that enables you to discover how much data is stored in the registry, or in any registry subtree, key or subkey. Additionally, the tool also enables you to search for all occurrences of a text string in the registry. This search can be limited to a specific subtree.
Note
DuReg counts data, not space. Because the space any data occupies varies with the storage method and amount of free space available, the size of data and size of space consumed are not equal. Also, because it measures data, DuReg does not account for fragmented free space in the registry.
The DuReg helps developers and administrators estimate how much space registry data is consuming. Developers can use this tool to discover how data they are contributing to the registry. Administrators can use this tool to investigate which applications are filling a registry when the registry approaches its maximum size.
The registry data size function is unique to each system. You can determine the maximum registry size and an estimate of the current registry size by using System in Control Panel. You can also find the current:maximum size ratio (expressed as a percentage) by using the System: % Registry Quota in Use counter in Perfmon\Sysmon. However, only DuReg returns the size of individual keys and subkeys.
