I think you must do it manually.
======================
The DeleteMenu function deletes an item from the specified menu. If the menu item opens a menu or submenu, this function destroys the handle to the menu or submenu and frees the memory used by the menu or submenu.
Syntax
BOOL DeleteMenu( HMENU hMenu,
UINT uPosition,
UINT uFlags
);
Parameters
hMenu
[in] Handle to the menu to be changed.
uPosition
[in] Specifies the menu item to be deleted, as determined by the uFlags parameter.
uFlags
[in] Specifies how the uPosition parameter is interpreted. This parameter must be one of the following values.
MF_BYCOMMAND
Indicates that uPosition gives the identifier of the menu item. The MF_BYCOMMAND flag is the default flag if neither the MF_BYCOMMAND nor MF_BYPOSITION flag is specified.
MF_BYPOSITION
Indicates that uPosition gives the zero-based relative position of the menu item.
Return Value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
The application must call the DrawMenuBar function whenever a menu changes, whether or not the menu is in a displayed window.
