Because of security reasons creating a new process
from Windows service isn't a simple task especially if
you need to run an application with GUI on Windows
2008/Windows Vista/Windows 7 under specific user
account.
DevxExec is designed exactly to run application from a
windows service. Using DevxExec you can run
applications from your service under Local System,
Network Service or a specific user account.
There is even possibility to specify a session for the
running application. Thus when multiple users
connected to the computer via remote desktop you can
specify on which desktop the application should be
started.
It has command line interface. To see the help, run
DevxExec with no parameters.
DevxExec is free for noncommercial usage.

DevxExec.exe /user: Administrator /password:qwerty
cmd.exe
