1 Always run USMT from an account with local administrator rights (Right-click Command Prompt and choose Run as Administrator) 2  Always make sure you have enough free space to store the migration data.  Try not to use expensive searches (i.e. don't search every drive for .exe files)
If you are only upgrading your operating system, USMT is not needed. So, bottom line, USMT captures and restores a users files and settings (user state) so that the migration to a newer version of Windows (or simply a newly installed copy of the same version) is as seamless as possible for the end user.
