Configure app which requires admin rights to run at startup with task scheduler


App which requires elevated admin rights can’t just be set to run at startup by adding it to the registry key (HKLM\Software\Microsoft\Windows\CurrentVersion\Run) because it mail fail to start since it requires the UAC prompt. Windows will silently fail to display the UAC prompt.
