Registry
Definition
The hierarchical configuration database used by Windows.
Detailed explanation
The Windows Registry is a hierarchical configuration database divided into system-wide and user-specific hives. Drivers and services can have keys describing startup, parameters, class settings, and device instances. Much of the data is managed by Windows servicing, Plug and Play, or applications rather than intended as a direct user interface. HKLM\SYSTEM contains service and device-control state used during startup, while per-user preferences commonly reside under HKCU. Transactional servicing, access control, and generated device-instance keys make the Registry a coordinated system database rather than a collection of independent text settings.
