About 80 to 90 percent of computers around the world have Windows as their operating system. While everyone enjoys the speed that a new computer has, as time passes you generally begin to experience a decrease is computer performance as well as an increase in unknown errors, crashes and blue screen messages.

While there are many things that can cause those problems like computer viruses and spy ware, most people do not pay any attention to their computer registry, which is the main cause.

The computer registry easy acts like a catalog or phone book of sorts, showing your computer exactly where to look for the files it needs to pull up and how to run programs.

It even holds information about your personal setting on your computer so you don't have to keep making changes every time you reboot your system. With every day use, errors can show up in the registry easy. No matter what you do the registry becomes progressively corrupt over time due to old or missing entries.

Now if you feel confident enough to do it, you can always go in and manually work on your registry easy. Unless you know what you are doing editing registry entries you should not attempt it. You might end up changing something vital that can cause your computer to not start up again.

Another way you can give your computer some new life is by increasing the amount of Random Access Memory or RAM your system has. This again can be tricky. Unless you feel comfortable enough opening up your computer case and messing around with the sticks of ram inside, then this probably isn't the option for you.

The most cost effective option is with a free registry scanner program. All it requires is the touch of a button and you will see a significant increase in your systems performance in just a few minutes as well as not having any more of those error messages or blue screens.

The software will not only fix the registry by deleting old entries, fixing corrupt entries but will also organize and shrink the registry down for faster access by your Windows Operating system, speeding up your computer further and keeping it free from errors.
