Every Windows-based PC has what is called a Windows registry. This registry is accessed everytime your computer starts and you install or uninstall a new program. The registry is basically a traffic director for your computer and it tells it where programs are and what needs to happen when they startup. As you use your computer, this registry begins harboring errors because most programs leave “excess” information in the registry thus slowing it down. The longer you use your computer, the more errors the registry will have.

While some consumers believe that the only way to correct a computer's performance issues is to take it in to a repair tech, many others know that easy-to-use registry cleaners can do the work for them at a fraction of what a repair tech will charge. Before you take it to a tech, compare the registry cleaners we reviewed and find the best registry cleaner for you serve your needs best.
