Understanding the Windows Registry

The Windows Registry is essentially a hierarchical database integrated into the Windows operating system. It stores low-level settings and configuration options for the OS itself, hardware devices, and many installed applications (both system-level and third-party). Developers utilize this database to store values in the form of Keys and Subkeys, which dictate how software and hardware behave.

Think of it as the central configuration hub. Changes made here can significantly impact system behavior, performance, and functionality. Both legitimate applications (like services, system optimizers) and potentially malicious software can interact with and modify the registry.
