If it's very silent it will reboot without asking. If a restart is necessary and the '/NORESTART' command isn't used (see below) and Setup is silent, it will display a Reboot now? message box. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with DisableStartupPrompt or the '/SP-' command line option explained above). When a setup is very silent this installation progress window is not displayed. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. Instructs Setup to be silent or very silent. Of course, this will have no effect if the DisableStartupPrompt section directive was set to yes. Do you wish to continue? prompt at the beginning of Setup. These can be useful to system administrators, and to other programs calling the Setup program. The Setup program accepts optional command line parameters.
