Try using DeleteMenu
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.
BOOL DeleteMenu(
HMENU hMenu, // handle to menu
UINT uPosition, // menu item identifier or position
UINT uFlags // menu item flag
);
Parameters
hMenu
Identifies the menu to be changed.
uPosition
Specifies the menu item to be deleted, as determined by the uFlags parameter.
uFlags
Specifies how the uPosition parameter is interpreted. This parameter must be one of the following values:
Value Meaning
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 Values
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.
