Edit:
i have a small question , is there a way to get the context menu for the drives and my computer?
Edit:
hi again
i tried modifying the code so i could pass the csidl then get ppidl using SHGetSpecialFolderLocation but it throws nullRefrence exception on oParentFolder in GetContextMenuInterfaces
so i used:
IShellFolder oDesktopFolder = GetDesktopFolder();
then used GetContextMenuInterfaces(oDesktopFolder, _arrPIDLs))
now using SHGetSpecialFolderLocation:
[DllImport("Shell32", EntryPoint = "SHGetSpecialFolderLocation",
ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
public static extern Int32 SHGetSpecialFolderLocation(
IntPtr hwndOwner, CSIDL nFolder, out IntPtr ppidl);
and the CSIDL enum:

public enum CSIDL
{

ADMINTOOLS = 0x30,
ALTSTARTUP = 0x1d,
APPDATA = 0x1a,
BITBUCKET = 10,
CDBURN_AREA = 0x3b,
COMMON_ADMINTOOLS = 0x2f,
COMMON_ALTSTARTUP = 30,
COMMON_APPDATA = 0x23,
COMMON_DESKTOPDIRECTORY = 0x19,
COMMON_DOCUMENTS = 0x2e,
COMMON_FAVORITES = 0x1f,
COMMON_MUSIC = 0x35,
COMMON_PICTURES = 0x36,
COMMON_PROGRAMS = 0x17,
COMMON_STARTMENU = 0x16,
COMMON_STARTUP = 0x18,
COMMON_TEMPLATES = 0x2d,
COMMON_VIDEO = 0x37,
CONTROLS = 3,
COOKIES = 0x21,
DESKTOP = 0,
DESKTOPDIRECTORY = 0x10,
DRIVES = 0x11,
FAVORITES = 6,
FLAG_CREATE = 0x8000,
FONTS = 20,
HISTORY = 0x22,
INTERNET = 1,
INTERNET_CACHE = 0x20,
LOCAL_APPDATA = 0x1c,
MYDOCUMENTS = 12,
MYMUSIC = 13,
MYPICTURES = 0x27,
MYVIDEO = 14,
NETHOOD = 0x13,
NETWORK = 0x12,
PERSONAL = 5,
PRINTERS = 4,
PRINTHOOD = 0x1b,
PROFILE = 40,
PROFILES = 0x3e,
PROGRAM_FILES = 0x26,
PROGRAM_FILES_COMMON = 0x2b,
PROGRAMS = 2,
RECENT = 8,
SENDTO = 9,
STARTMENU = 11,
STARTUP = 7,
SYSTEM = 0x25,
TEMPLATES = 0x15,
WINDOWS = 0x24

}
u could retreive the context menu of various shell item. Enjoy!
