What causes a registry error?


The Windows registry is the nerve center which is used to store options and settings for software configuration, system hardware, system and network settings, user preferences and more. When you install an application, the associated new registry entries will be created. These entries should automatically be deleted when you uninstall the application. Unfortunately, it does not always work that way. Sometimes, you will find that some applications fail to remove their own registry entries. These entries then become obsolete. Over time, the Windows registry begins to accumulate data that are invalid and obsolete. The invalid data eventually piles up within the registry, slowing Windows down, compromising computer performance and causing other computer problems. To keep your computer at top performance, it is recommended that you periodically clean the Windows registry and fix any registry entries if necessary.
