There is no official Windows update to add GetSystemTimePreciseAsFileTime to Windows 7. This function was first introduced in Windows 8 and is not present in the kernel32.dll of older operating systems.

But what if you need to support Windows 7? Can you use this function safely? The short answer is: Not without a specific update.

Third-Party Libraries: Popular libraries like SDL or libuv began using this API for better timing, inadvertently breaking compatibility with older OS versions. Can You "Update" Windows 7 to Support It?

Update Visual C++ Redistributable: Download the latest Visual C++ Redistributable from Microsoft Support.

"The procedure entry point GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll" Why it happens now

📦 Required update

You need KB3033929 (or later cumulative updates) to enable it.
Without this update, GetSystemTimePreciseAsFileTime is not present in kernel32.dll, and your code will fail at runtime.

There are two practical compatibility approaches for applications that need this function on Windows 7:

void GetHighResSystemTime(FILETIME *ftOut) if (preciseTimeFunc) preciseTimeFunc(ftOut); else // Fallback logic: hybrid QPC + GetSystemTimeAsFileTime // (Implementation omitted for brevity)
