For new applications, dynamic loading of the function provides the best of both worlds: microsecond precision when available, seamless fallback when not.

The most reliable way to run the software without modifying your system files is to install the previous release that still maintains Windows 7 compatibility. getsystemtimepreciseasfiletime windows 7 upd

Don't assume it’s present. Use:

// Read initial time base at app startup LARGE_INTEGER freq, qpcStart; FILETIME ftStart; QueryPerformanceFrequency(&freq); QueryPerformanceCounter(&qpcStart); GetSystemTimeAsFileTime(&ftStart); // Later: compute elapsed QPC, convert to FILETIME offset For new applications, dynamic loading of the function

If your application requires sub-millisecond precision on Windows 7, the standard fallback isn't enough. In this case, developers often combine GetSystemTimeAsFileTime (for the absolute date/time) with QueryPerformanceCounter (to calculate the high-resolution offset). For new applications
