Description
Using this function you can determine whether your system requires a restart or not. This can be useful when you are running external setup applications or want to check whether previously installers applications require a restart.
To check whether your own installer requires a restart (when using /REBOOTOK parameters), use IfRebootFlag (see documentation).
