[PATCH v5 2/2] shell32: ShellExecute uses SW_SHOWDEFAULT by default This patch applies to applications that launch processes via ShellDispatch specified as VT_EMPTY type (such as WPS PDF Editor). It prevents the conversion of VT_EMPTY type to the INT_4 value of 0 (i.e., SW_HIDE), which would otherwise cause the main program window not to be displayed.
