I don't have example of Win32_ProcessStartup. But if you only want to hide the windows, CreateProcess has the ability to do that.
Set the STARTUP_INFO structure with this

c0 = chr(0)
lpStartupInfo = Num2DWord(68) + replicate(c0, 40)
lpStartupInfo = lpStartupInfo + Num2DWord(1)
lpStartupInfo = lpStartupInfo + replicate(c0, 20)
Ret = CreateProcess(0, Instance, 0, 0, 1, HIGH_PRIORITY_CLASS, 0, 0, @lpStartupInfo, @process_info)
