pszSubKey

pszSubKey is a string identifier used within the Windows Registry to represent a specific subkey. The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. Each key in the registry can contain other keys, which are referred to as subkeys. The pszSubKey string is typically used by Windows API functions or programming libraries to point to the location of a particular subkey within this hierarchy. For instance, when working with registry manipulation functions in C or C++, a character pointer (often denoted by `psz` prefix in variable names, indicating a pointer to a string) might be passed to specify the exact path to a subkey you wish to access, modify, or create. Understanding pszSubKey is crucial for developers who need to interact with the Windows Registry programmatically to configure application settings, manage system parameters, or store persistent data. It essentially serves as a label or address within the registry's structure.
