Change the dwFlags of STARTUPINFO

[KamenRiderKuuga]

Nothing happened after I adjusted the wShowWindow property to SW_MINIMIZE, and I found something description of wShowWindow property in MSDN:

If dwFlags specifies STARTF_USESHOWWINDOW, this member can be any of the values that can be specified in the nCmdShow parameter for the ShowWindow function, except for SW_SHOWDEFAULT. Otherwise, this member is ignored.
