function LastInput: DWord;
var
  
LInput: TLastInputInfo;
begin
  
LInput.cbSize := SizeOf(TLastInputInfo);
  GetLastInputInfo(LInput);
  Result := GetTickCount - LInput.dwTime;
end;


//Example:
procedure TForm1.Timer1Timer(Sender: TObject);
begin
  
Label1.Caption := Format('System Idle since %d ms', [LastInput]);
end;


// The GetLastInputInfo function retrieves the time
// of the last input event.
// Minimum operating systems: Windows 2000
