Many do not understand what exactly a registry repair cleaner cleans nor why it is so important. Actually, most people who use their computers everyday aren't familiar with this tool. You usually only learn about a registry repair cleaner when you are having computer trouble and really need one. Unfortunately, the problems that caused you to look for a registry cleaner could have been avoided if one had been utilized consistently.

Reading about a registry is the first step before knowing the function of a registry repair cleaner. Microsoft Windows is the most common OS and every PC using this system has a registry. A registry is one of the most important components of a Windows operating system. Without a registry, Windows would not be able to run.

Think of the registry as the attic that Windows uses as storage for data and information. When it needs to find something, such as the holiday decorations as an analogy, it is in the store room right where it should be. Some things that might be stored in the "garage" are: all of the system configurations, preferences and settings, along with hardware drivers, certain info about start up applications and any software information on installation and shortcuts, to name a few.

Using your computer more increases how much data and how many files are added to the registry. If you think deleting software or a program will remove it completely, you may be wrong. Oftentimes it just doesn't take it away completely. Often what happens is that even after removing the software or the files there is some data left over in your registry. There is no purpose for this data to still be there. Even though it has been deleted from your computer, it is still there taking up space in your registry.

Your registry will try and maintain it all but it will end up causing some issues for your operating system. You may notice things going on with your computer that you haven't experienced prior to this. If you get an error message that alerts you to the registry issue, count yourself lucky. Most often, this is not the case and you will see things that present themselves much more subtly and slowly. You may have noticed some of the following registry related issues: programs and app's taking too long to open or not opening, software and/or app's crashing with a message that an error has occurred, a very slow computer is a warning of registry issues, and the worst one of all, when your OS crashes. (This will show itself with a blue screen.)

Problems like these can be fixed before they manifest and you can be spared the headache of having to fix them later. It is really simple: buy a registry repair cleaner. The main goal of this kind of software is to empty your registry of files and data that are not necessary and to keep your computer and operating system performing at their best.
