Cleaning up your computer is important. It’s the best way to improve performance, especially if it has been slowing down over time.  If you’re not happy with the performance of your computer then I definitely suggest that you look into a program like the one featured in our RegCure review.  This program is truly the best registry cleaner that you can find.  A registry cleaner is a specific tool that helps people to clean out their registry in Windows.  The registry is a complex database of files that help Windows run your software and hardware with consistent settings.  However it can get cluttered.
