Changes

During the Windows Server 2008 upgrade process the files, folders and applications associated with the previously installed Windows version are relocated to a ''windows.old'' folder and all user settings stored. Once this task is complete, a clean installation of the new operating system is performed and the saved user settings migrated to the new environment. Upon completion of a successful upgrade the Windows Server 2008 system will include all applications, settings and user files from the previous operating system installation.

At any point during the setup process (except when the installation is actually being performed) ''Shift+F10'' may be pressed to gain access to the command-prompt. From within this command prompt window most of the standard Windows Server 2008 command-line tools are available allowing tasks to be performed that might otherwise not be possible from within the setup interface. A full list of available commands and respective descriptions can be found in the chapter entitled [[Windows Server 2008 Command-line Tools]].
