As computers have become more complex, so have the methods of storing this data. The few settings needed by MS-DOS were stored in the plain text file CONFIG.SYS. DOS programs had to make their own arrangements for storing user settings. Windows NT kernels support redirection of INI file-related APIs into a virtual file in a Registry location such as HKEY_CURRENT_USER using a feature called “InifileMapping”. In addition to simply storing application settings, the registry is the means by which programs and components locate other programs and components.
