Sometimes an autoloader you've unchecked--perhaps days or weeks ago--will reappear on the list later. Why? Because the program that put it there in the first place senses that it's no longer autoloading and corrects your "mistake." In these cases, examine that program's Options or Preferences menu and look for something like "Launch when Windows loads" or "Put in System Tray." Uncheck that option.

What else can slow down a once-fast boot? An overloaded or corrupted Registry. But Registry cleaning is inherently dangerous, and I don't recommend it unless things have become unbearable. See for details.
