news 来源：原创 2025/6/10 2:02:03

    // Remove "Customize This Folder..." if folder is not customizable.
    if (!_CachedIsCustomizable())
    {
        // The Folder Option "Classic style" and the shell restriction WIN95CLASSIC
        // should be the same. (Per ChristoB, otherwise admin's never understand what
        // the restriction means.) Since we want this to change DEFAULTs, and still
        // allow the user to turn on Web View, we don't remove the customize wizard here.
        int iIndex = MenuIndexFromID(hmenuView, SFVIDM_VIEW_CUSTOMWIZARD);
        if (iIndex != -1)
        {
            DeleteMenu(hmenuView, iIndex + 1, MF_BYPOSITION); // Remove Menu seperator
            DeleteMenu(hmenuView, iIndex,     MF_BYPOSITION); // Remove Customize
        }
