Step-by-step explanation:
The utility that allows you to transfer user settings over to Windows Vista after an upgrade and can use scripted files is Windows Easy Transfer. This utility is specifically designed to simplify the process of transferring files, settings, and user accounts from an older version of Windows to Windows Vista.
Windows Easy Transfer uses a wizard-based interface to guide you through the process. It can transfer a wide range of data, including user accounts, files and folders, program settings, and even internet settings.
