Actually really useful. After downloading the software, there are no more blue screen crashes, no more "2-minute start-up". I really love it! If you have the same problems with your computer, why not just spend two minutes to download it and it will smartly help you to solve these problems. Thus, you will find your life easier. Believe me, it worth a try.
