Is there a really-really-really-don't-reboot parameter for msiexec?



In the IT world, it is often necessary to make changes to computers and networks that require reboots. For example, when an application needs to be installed or updated, a reboot may be required in order for the changes to take effect. However, for many IT administrators, this presents a problem: how can they ensure that the reboot does not occur at an inconvenient time? Fortunately, there is a way to prevent reboots from occurring when using the Windows installer, MSIExec.

MSIExec is a command-line utility which is used to install, update, or uninstall Windows applications. It is the backbone of Windows Installer, the Microsoft component which provides a standard way for software packages to be installed or updated on Windows systems. By default, MSIExec will prompt the user to reboot the system after installation is complete. This can be inconvenient for IT administrators who are trying to install or update software on multiple systems.

Thankfully, there is a parameter available which can be used to prevent the reboot prompt from appearing. The parameter is called REBOOT=ReallySuppress and it can be used in the following command line format:

msiexec /i REBOOT=ReallySuppress

This parameter will prevent the Windows installer from prompting the user to reboot the system, even if a reboot is required. This is especially useful for IT administrators who need to install or update software on multiple systems, as it allows them to install the software without having to worry about reboots.

It should be noted that using the REBOOT=ReallySuppress parameter does not guarantee that a reboot will not be necessary. If a reboot is required for the changes to take effect, then the user will still be required to reboot the system. However, using this parameter will prevent the Windows installer from prompting the user to reboot the system.

In summary, the REBOOT=ReallySuppress parameter can be used to prevent the Windows installer from prompting the user to reboot the system after installation is complete. This is especially useful for IT administrators who need to install or update software on multiple systems, as it allows them to install the software without having to worry about reboots. Of course, this parameter does not guarantee that a reboot will not be necessary, but it can help to ensure that the user does not have to be prompted to reboot the system.
