[PATCH v3 0/1] MR9997: shell32: ShellExecute uses SW_SHOWDEFAULT by default

[Fan Zhou (＠zhoufan_uniontech)]

This patch applies to applications that launch processes via ShellDispatch without specifying a display mode (such as WPS PDF Editor). 

When no show parameter is specified, VT_EMPTY is converted to the integer 0 (i.e., SW_HIDE), causing the main window to be hidden by default. This behavior is now adjusted to use the default show mode. 

The modification references Microsoft’s official description of the IShellDispatch2.ShellExecute interface: "If this parameter is not specified, the application uses its default value."
