Var
  hSysMenu : hMenu;
  NCT: Integer;
Begin
    hSysmenu := GetSystemmenu(HandleOfYourWindow,False);
    Nct := Getmenuitemcount(hSysmenu);
    Deletemenu(hSysmenu,NCT-1,MF_BYPosition);
    //Plockar bort Separatorn på fönstret
    Deletemenu(hSysmenu,NCT-2,MF_BYPosition);
    //Redraw the Menu
    Drawmenubar(HandleOfYourWindowAgain);
End;

That's for removing items the last 2 items in the menu...

Enabling and disabling is similar to Deleting...
just replace Deletemenu with
  EnableMenuItem(hSysMenu, NCT-1, MF_BYPOSITION OR MF_DISABLED);
Or
  EnableMenuItem(hSysMenu, NCT-1, MF_BYPOSITION OR MF_ENABLED);
 
There are other Constants than MF_BYPOSITION in play aswell but check out the MSHelp for EnableMenu item and you'll get the full picture..

Adding items is no breeze...you will need to hook some WM_Message targeted for the window..
Haven't done that before so i don't really know how to do it...i've investigated some but my memory is clouded.. ;P
