Answer 1

SHGetDesktopFolder取回收站对象，然后用IShellFolder::GetUIObjectOf取右键菜单对象。
接着执行还是弹出就看你的了。
下面是打开回收站属性的示例代码void ShowRecycleBinShellProperties()
{
HRESULT hr; // Call this if needed.
::CoInitialize( NULL );

IShellFolder* pDesktopFolder = NULL;
IMalloc* pMalloc = NULL; hr = ::SHGetMalloc(&pMalloc); // Get desktop folder.
hr = ::SHGetDesktopFolder(&pDesktopFolder); // Get the history folder.
ITEMIDLIST* pidlRecycleBin = NULL;
hr = ::SHGetSpecialFolderLocation(NULL, CSIDL_BITBUCKET, &pidlRecycleBin); {
IContextMenu* pContextMenu = NULL;
const ITEMIDLIST* pidl2 = pidlRecycleBin;
hr = pDesktopFolder->GetUIObjectOf(NULL, 1, &pidl2, IID_IContextMenu, NULL, (void**)&pContextMenu);
if (SUCCEEDED(hr))
{
CMINVOKECOMMANDINFO pCommandInfo = { 0 };

pCommandInfo.cbSize = sizeof(CMINVOKECOMMANDINFO);
pCommandInfo.lpVerb = _T("properties");
pCommandInfo.fMask = CMIC_MASK_FLAG_NO_UI; // has no effect
hr = pContextMenu->InvokeCommand(&pCommandInfo);
}
pContextMenu->Release();
} // Get the IShellFolder of the history folder.
IShellFolder* pRecycleBinFolder = NULL;
hr = pDesktopFolder->BindToObject(pidlRecycleBin, NULL, IID_IShellFolder, (void**)&pRecycleBinFolder);
pRecycleBinFolder->Release();
pMalloc->Release();
pDesktopFolder->Release();
}

右键菜单
以单文档程序为例   
  一、添加菜单资源   IDR_POPMENU，在资源编辑器中编辑菜单第一列，并且为每个菜单项添加处理函数。   
  二、在   CView   派生类中添加   WM_RBUTTONDOWN   消息处理函数，添加代码：   
  CMenu   menu;   
  menu.LoadMenu(   IDR_POPMENU   );   
  CMenu   *pPopupMenu   =   menu.GetSubMenu(   0   );   
  ClientToScreen(   &point   );   
  pPopupMenu   ->   TrackPopupMenu(   TPM_RIGHTBUTTON,   point.x,   point.y,   this   );   
  pPopupMenu   ->   DestroyMenu();
