The system registry is the central storage for all configuration data. The Windows system configuration, the computer hardware configuration, configuration information about Win32-based applications, and user preferences are all stored in the registry.
The registry contains ordered pairs of keys and their associated values that are manipulated through the Win32 registry application programming interfaces (APIs). For example, the registry might have a Wallpaper key with an associated value of Work.bmp, meaning that the current desktop background is configured to use the Work bitmap.
The EasyReg component allows you to read and write registry keys and
values to the system registry.
The new EasyReg is small and fast. It does not depend on any external library, but still
maintains the powerfull COM interface to allow scripting languages
(such as MS Visual Basic) and scripting capable languages (such as C++) easy access to its
functions.
