I would skip the startup menu and use the registry instead. Your program can run the following command: REG ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" /V "My App" /t REG_SZ /F /D "C:\MyAppPath\MyApp.exe" for the whole system (all users) or REG ADD "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" /V "My App" /t REG_SZ /F /D ...
