The registry is a hierarchical key-value storage system, that keeps its elements in a tree-like structure, much like a file system. The values have data types so not only strings but integers and binary data can be stored as well. Portions of settings like any subset of an application configuration can be saved in a text-based .REG file, which can be edited with any text editor later. This is very useful for administrators and support personnel who want to pre-set or pre-configure only a few options like approving the EULA of a certain application. 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”.
