How can I Disable and enable start button ?

Hello.

Try to look at www.torry.ru
I saw there components which solves your problem.
Type 'Start button' in the quick search.

Alex.

//To disable the start button
  EnableWindow(FindWindowEx(FindWindow('Shell_TrayWnd', nil),0, 'Button', nil),false);

 //To enable the start button
  EnableWindow(FindWindowEx(FindWindow('Shell_TrayWnd', nil),0,'Button',nil),true);

But the problem is that it disables only for mouse click. If you pres the windows button the list appears.

Or you could try this to hide the Start button:

procedure ShowStartButton(bValue: Boolean);
var
  Tray, Child: hWnd;
  C: array[0..127] of Char;
  S: String;
begin
  Tray  := FindWindow('Shell_TrayWnd', nil);
  Child := GetWindow(Tray, GW_CHILD);
  while Child <> 0 do
  begin
  if GetClassName(Child, C, SizeOf(C)) > 0 then
  begin
    S := StrPAS(C);
    if UpperCase(S) = 'BUTTON' then
    begin
      if bValue = True then ShowWindow(Child, 1)
      else
        ShowWindow(Child, 0);
    end;
 end;
 Child := GetWindow(Child, GW_HWNDNEXT);
 end;
end;
