I am looking for a way to have Microsoft Virtual PC 2004 start and
continue to run a virtual machine (or multiple virtual machines) in
the background of a machine.

I would really like to do this, but haven?t had the time to experiment
with it and figure out a solid way.

There are several ways that I imagined one could go about doing this? 
here are the possibilities that I have dreamed up for solving this:

-Run virtual pc as a service that starts up automatically and runs in
the background (passing ?pc ?pcname? launch).  I am not really sure if
this approach is plausible (because the ?virtual monitor? would have
to go somewhere..).

-Have the ?real windows? setup so that it would login to an account
automatically (at startup) and run the startup scripts (which would
just contain shortcuts to launch the virtual pcs)  I don?t really want
this user to be logged in, though? It would be nice if they would be
logged in, in the sense that they are fast user switched out, and
still have the applications running in that user?s session?  The only
way this could work well for me, though, is if (during startup) it
wouldn?t show that a user logging in running the programs and fast
user switching out (because someone could control the system while it
is doing that?)

-Any other approaches are welcome.

Thank you.
