: Introduced in Windows 8, WNF is a system-wide infrastructure that allows components to exchange state information asynchronously.
The software must be run on a modern version of Windows (Windows 10 or 11), or the developer must implement runtime checking via GetProcAddress instead of hard-linking the function. 2.

: Points to a scope identifier (SID for user scope, process ID for process scope). If NULL , WNF uses the current caller's identity to determine scope automatically. This parameter enables cross-process reading when proper permissions are in place. General ntdll
follows this bit layout:
Instead of hard-linking the function, load it explicitly at runtime. This practice checks if the API is available before execution to prevent application crashes.
