надо его вручную дорисовать

procedure GetScreenImage(bmp: TBitmap);
var
  CI: TCursorInfo;
  Icon: TIcon;
  II: TIconInfo;
  r: TRect;
begin
bmp.Width:= Screen.Width;
bmp.Height:= Screen.Height;
BitBlt(bmp.Canvas.Handle,0,0,Screen.Width,Screen.Height,
GetDC(GetDesktopWindow),0,0,SRCCopy);
//дорисуем курсор
Icon:=TIcon.Create;
r:=Rect(0,0,GetSystemMetrics(SM_CXSCREEN),
            GetSystemMetrics(SM_CYSCREEN));
CI.cbSize:=SizeOf(CI);
if (GetCursorInfo(CI)) and (CI.flags=CURSOR_SHOWING) then
 begin
  Icon.Handle:=CopyIcon(CI.hCursor);
  if GetIconInfo(Icon.Handle,II) then
  bmp.Canvas.Draw(ci.ptScreenPos.x - Integer(II.xHotspot) - r.Left,
                  ci.ptScreenPos.y - Integer(II.yHotspot) - r.Top,
                  Icon);
 end;
end;

// 1. Get the handle to the current mouse-cursor and its position

        GetIconInfo(CursorInfo.hCursor, IconInfo);
        // Draw the Cursor on our bitmap 
        ABitmap.Canvas.Draw(CursorInfo.ptScreenPos.X - IconInfo.xHotspot,
                            CursorInfo.ptScreenPos.Y - IconInfo.yHotspot,

// Example: Capture the screen and include the cursor. 
// Show the Screenshot in Image1
