How to exit app when Windows screen is locked?

I've inherited a Windows computer with a custom app on it. When the computer boots up the app launches almost immediately. When it launches it 'locks' the screen so I can't force the task bar via Windows key or Alt-F4. The app's configure file contains this:

cmdline -popupwindow  killexp true  

How can kill/exit the app so I can change some Windows settings?
