Registry is the most significant component of Microsoft Windows XP operating system, which contains information regarding operating system and all the applications that are installed and running on it. It is the fundamental component, which is refereed by the operating system for recognizing application data and permissions related to particular application. In some cases, you might need to clean or modify Windows registry to resolve some issues. Incorrect editing of registry might cause severe damage to the operating system and you come across critical situations if you do not have proper backup of registry. In such cases, system could not start up and you come across data loss scenarios. In order to overcome these circumstances, it becomes essential for you to carry out Data Recovery using appropriate tools.

Windows XP continuously communicates with the registry to start and stop applications. It gives parameters regarding the application to operating system. But Windows XP does not take any measure to clean registry, which supplies necessary information. If the registry contains a lot of unused information, which is inaccurate and incorrect, operating system might experience a number of issues.

When any application is installed on Windows XP computer, at least one registry hive is created. Depending upon the size of application, number of registry entries might be more than one. Every time when you modify application's configuration, either a new entry is created or the old one is updated. In such cases, getting response of a request become critical and thus your system becomes slow.

In theory, it is said that all registry hives related to any application are deleted but practically most of the applications do not take required steps to delete registry hives completely. Traces of the applications, which you uninstalled, would still be available in Windows registry.

In these cases, editing or removing unused registry is required. For this purpose, you can go for commercial registry cleaners that are compatible with Windows XP. But some users try to manually edit or remove the registry entries. This is not possible for everyone, because it requires high technical expertise. If you do not have complete information about registry and try to edit it incorrectly, you may come across grave situations that cause data loss and requireHard Drive Recovery to be sorted out.

Data Recovery in such cases is best possible through powerful and advanced third party recovery applications. These software are built with self-descriptive graphical user interface and thus are very easy to use. These disk recovery software do not alter original contents or write anything on hard drive as they have read-only conduct.
