(Microsoft terminology).. huh! Confused? Well, let me explain it in simple terms, which will make more sense.

Windows 3.x and MS-DOS stored configuration settings in text-based files like .ini ,autoexec.bat,config.sys. The registry is introduced to replace most text-based configuration files.

For instance, the windows registry contains information on user accounts, typed URLs, network shared, and Run command history.
