Microsoft Resource Kits - Windows 2003 Resource Kit

Regini.exe  (Windows 2003 Resource Kit)

The Window Server 2003 Resource Kit is a set of tools that system administrators and engineers use to manage or support a Windows Server 2003 system. Use it to streamline management tasks such as troubleshooting operating system issues, managing Active Directory, configuring networking and security features, and automating application deployment.
Regini.exe - Registry Change by Script
This tool uses character-based batch files to add keys to the Windows 2000 registry by specifying a registry script. You can use a registry editor (RegEdit or RegEdt32) to perform similar tasks as an interactive process, but RegIni supports a wider range of data types than the registry editors do. RegIni also provides a quick way to add or modify drivers in the registry.
