Who would have ever thought that your computer operating system would be to blame for your computer running slow? Well guess what - it is. Your computer's operating system is designed to work as flawlessly as possible but unfortunately that isn't the case. What happens is that when you fir get your computer there really isn't anything on it and so if runs smoothly. The problem happens the more that you use it because junk starts to build up all over the computer in many different areas and this makes your computer run inefficiently. This is why people are so attracted to the idea of registry cleaners - they are designed to clean one area of your computer that runs inefficiently, but unfortunately it only cleans "one" area of your computer when there are many other areas that need to be taken care of. This is why after you use a registry cleaner your computer really isn't that much faster.
