STARTF_TITLEISAPPID top-level constant
The lpTitle member contains an AppUserModelID. This identifier controls how the taskbar and Start menu present the application, and enables it to be associated with the correct shortcuts and Jump Lists. Generally, applications will use the SetCurrentProcessExplicitAppUserModelID and GetCurrentProcessExplicitAppUserModelID functions instead of setting this flag.
const STARTF_TITLEISAPPID = 0x00001000;
