The Windows User State Migration Tool is an excellent tool for those who will change PC and want to migrate Windows accounts along with personal settings for each user.
This tool is available from Microsoft itself and suitable for experienced users and system administrators. Despite being made through command line, is much more effective than the graphical tool that comes with Windows, it is limited to a single user settings and migrates much less.
This tool is also useful for those who will migrate from Windows XP 32 bit for Windows Vista 64 bits, since this does not allow the migration upgrade.
