You can use Microsoft® Windows® User State Migration Tool (USMT) 3.0 to migrate user files and settings during large deployments of Microsoft Windows XP and Microsoft Windows Vista® operating systems. USMT captures desktop, and application settings, as well as user accounts and users' files, and then migrates them to a new Windows installation. Using USMT can help you improve and simplify your migration process. You can use USMT for both side-by-side and wipe-and-load migrations. If you are only upgrading your operating system, USMT is not needed.
