HELP!!!!!!!

I'm making a application that runs on Windows Startup it must run after you have logged on and before the other applications! It must also stop the next starting programs before ending the program

[Lafor]

after you've written the app, just put a shortcut
of the executable in your startup menu... And the
app will start after you've logged in...

I am not sure what you mean by the following statement
"It must also stop the next starting programs before ending the program"
