As time goes by, as you have been using your computer on a regular basis, your PC registry will eventually start to cause you some problems. It is not a defect with your system but a natural occurrence whenever something is being used too often. Eventually, some of its parts will start to cause errors. When this happens, you need to conduct a PC registry cleanup which is actually an easy thing to do, if you have the right software for it.

Windows based operating systems have this so called registry, and it is there for a great purpose. It is a large database of files necessary to keep your system working properly. What it does actually is to record every footprint of an action that is done on your computer. So whenever you open a program, it is recorded in the registry. When you use your word processor to type a document, your registry takes note of that. When you surf the web, it is also recorded there; especially when you conduct certain actions that require some files to be changed, like for example, if you need it to be installed or deleted.

The problem with the registry occurs when it becomes too loaded with files, especially files that are no longer being used because it takes too much of the system's resources to read these unused files anyway. These files are actually leftovers when you uninstall some software programs because not all the files of an application are completely removed. When these files are left in the system, it takes up space as well as system resources. Such things will cause your computer to eventually freeze up and it all happens within the PC registry.

In order to keep your registry clean and running smoothly, you need a registry cleaner which is a program that scans and cleans your registry. It helps maintain your registry in peak form, keeping errors at bay and any computer freezes from ever happening.
