Microsoft Windows 2000 stores hardware and software settings centrally in a hierarchical database called the registry. The registry replaces many of the .INI, .SYS, and .COM configuration files used in earlier versions of Microsoft Windows. The registry controls the Windows 2000 operating system by providing the appropriate initialization information to start applications and load components, such as device drivers and network protocols.
USING REGISTRY EDITOR
Most Windows 2000 users never need to access the registry. However, management of the registry is an important part of the system administrator's job and includes viewing, editing, backing up, and restoring the registry. You use Registry Editor to view and change the registry configuration.
