Are you aware that this won't work on Terminal Services or when Windows

IMHO, you're trying to cure the symptom instead of curing the disease.
What you should do is fixing your "launch from a service" system so
that it can launch your programs in every circumstances. What happens
now if the user log off and another user log on?
Wouldn't it far more simple to have in the "Startup" folder of
Everybody's Start Menu a "run as" batch or something similar that would
run the programs when a user log on, instead of relying on a service?
