It depends on the nature of the welcome message. If the output is into the console windows, then redirecting the out put might work or calling the application with START /MIN /WAIT might also work. However, fi the output is some kind of splash screen or message box then I don't think you'll be able to suppress it.

However, if you schedule the application with the Task Scheduler and run it under another user account then there will be no feedback at all on the current user's desktop for that application since it'll only interact with it's own (non-existent) desktop.
