The Registry is Windows’ configuration database, and the Native API lets you operate on it with surgical precision. In this module Pavel demystifies its hive-backed architecture, then leads you through opening, creating, editing, and enumerating keys and values without a single Win32 call. You’ll set up change notifications for instant event-driven reactions and wrap multiple edits inside kernel-level transactions for all-or-nothing safety. By the end you’ll wield the same low-level operations used by installers, services, and malware alike-perfect for configuration tools, forensic collectors, or stealthy persistence tricks.
