Tomcat76: You know how right after you install Windows, setup presents you with "Welcome to Windows"? Sysprep, or System Preparation Tool, is a corporate deployment tool used by system administrators to prepare a system for duplication or delivery to the customer. Essentially, it configures the computer to run Windows Welcome or Mini-Setup the first time the end user restarts the computer ('Microsoft Out-of-Box Experience', or OOBE). When you restart the computer, Windows will present a shortened form of GUI-mode Setup.
