If you are writing software that must run on both Windows 10/11 and Windows 7, you cannot call this function directly, or your program will fail to start on Windows 7 with an "Entry Point Not Found" error in Kernel32.dll 1. Dynamic Linking (The Safe Way) Instead of linking to the function at compile-time, use GetProcAddress to see if the function exists at runtime. VOID (WINAPI *PGETSYSTEMTIMEPRECISE)(LPFILETIME); GetBestTimestamp(LPFILETIME ft)
Load the function at runtime with GetProcAddress . Fall back to GetSystemTimeAsFileTime + QueryPerformanceCounter hybrid if not available. This ensures compatibility across all Windows 7 SP1 systems (patched or not). getsystemtimepreciseasfiletime windows 7 upd
