In Windows operating systems (OS), the registry is a central hierarchal database that stores configuration information related to system, user profiles, applications, and software on the system. OS utilizes the registry to store both static data similar to environment variables and dynamic data such as information related to system performance. Windows XP and the applications running on it constantly use the registry to query, read and write information to and from the registry.

With continuous and regular use, a lot of unwanted information starts accumulating in the registry. This leads to unwarranted registry growth pertaining to obsolete entries related to hardware, software, ActiveX and OCX controls, invalid DLLs and shortcuts, and empty keys. This growth and increase in undesired information makes the registry corrupt and fragmented. Due to this, the registry becomes unstable and starts generating errors on your PC. In severe situations, the registry can even crash and render your system unusable.
