Microsoft is adopting a consistent set of command-line
switches that you can use to deploy packages that contain software updates,
such as security updates, critical updates, and hotfixes. This article
describes these new command-line switches and their behaviors.Note
Packages that support these new command-line switches also
support earlier command-line switches for backwards compatibility. However,
usage of the earlier switches should be discontinued as this support may be
removed in future software updates.

IExpress packages, click the following article number to view the article in

Description of the standard terminology that is used to describe Microsoft software updates
Microsoft is adopting the following command-line switches
for software update packages:
- /help; /h; /? - Displays a dialog box that shows the correct usage of the Setup
command, including a list of all its command-line switches and their behaviors.
You can display this help information in the command-line interface (CLI) or
the graphical user interface (GUI). If you use any command-line switch
incorrectly, this help switch is invoked and the correct usage is displayed.
The dialog box also provides references to more online information.
- /quiet - Runs the Setup program or the removal program in "quiet" mode.
The program does not prompt the user with any messages. The program enters all
messages in a log file. By default, the program restarts the computer with no
prompt or warning if the process requires a restart for the changes to take
effect. To change the default restart behavior, use a different restart
- /passive - Runs the Setup program or the removal program in "passive"
mode. The program does not prompt the user with any error messages. The user
sees a progress bar that indicates that the installation or the removal is
occurring. The user cannot cancel the installation or the removal. By default,
the program invokes the /warnrestart switch. If the program is installing multiple updates, the
progress bar indicates the progress of the installation or the removal for each
- /norestart - Does not restart the computer after the installation or the
removal, even if the process requires a restart for the changes to take
- /forcerestart - Restarts the computer after the installation or the removal,
even if the process does not require a restart for the changes to take effect.
Restarting forces programs that are running to close.
- /warnrestart[:x] - Invokes a dialog box that warns the user that a restart will
occur in x seconds (in 30 seconds if no value is
specified). For example, to warn that a restart will occur in 60 seconds, type
/warnrestart:60. The dialog box contains a
Cancel button and a Restart Now button. If
the user clicks Cancel, the computer is not
- /promptrestart - Prompts the user that the computer must be restarted for the
changes to take effect. The user can select whether to restart the computer.
- /uninstall - Removes the package.
- /log - Enables the user to define the path for the local log file.
This switch invokes the default logging behavior.
- /extract - Enables you to extract the installation files to a specified
