How to move wpf application into minimize tray at Window Start-up?

I have created setup of my application using Windows Installer.
Now I want to Start application at Windows Start-Up and move it system
minimize tray as i don't want to display GUI(View) at Windows Start-Up.
I have searched in Google and i found to use Registry key But that is not
enough for me as i also want to move to system minimize tray and
application run.
My purpose to do it is, user feels annoying when application starts every
time when he/she starts system.
Can anyone have answer? Thanks..
