Microsoft backported GetSystemTimePreciseAsFileTime to Windows 7 via (released March 2015). This update was primarily released to address SHA-2 code signing support, but it also added several new APIs to the platform, including our high-precision time function.
// 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
#include <windows.h> #include <stdio.h>
This creates a significant compatibility gap when modern applications built with newer Windows SDK versions attempt to run on Windows 7. The error message appears as: getsystemtimepreciseasfiletime windows 7 upd
to the Microsoft Update Catalog if you prefer searching by KB number.
"QueryPerformanceCounter returns system time." Truth: QPC returns elapsed counts, not wall-clock time. It drifts if uncorrected.
If you are trying to run a modern application, game, or software development tool on Windows 7 and encounter an error stating that GetSystemTimePreciseAsFileTime is missing or could not be located in API-MS-WIN-CRT-TIME-L1-1-0.DLL , you are facing a common issue related to outdated system components. The error message appears as: to the Microsoft
There is that adds GetSystemTimePreciseAsFileTime to Windows 7. It remains an exclusive API function introduced in Windows 8. However, you can use several reliable workarounds, system updates, and coding fallbacks to bypass or resolve this crash. Why the Error Happens on Windows 7
Here is the critical distinction developers must understand:
, this function is designed to provide the highest possible level of precision (less than 1 microsecond) for the current system date and time. Before this, developers typically used GetSystemTimeAsFileTime If you are trying to run a modern
if (!initialized) HMODULE hKernel32 = GetModuleHandleW(L"kernel32.dll"); if (hKernel32) pFunc = (FnGetSystemTimePreciseAsFileTime)GetProcAddress(hKernel32, "GetSystemTimePreciseAsFileTime");
, an API wrapper designed to improve compatibility for newer applications on Windows 7. Older Software Versions
This simple function accepts a pointer to a FILETIME structure that receives the current system time with high precision.
