By employing runtime dynamic linking and a robust fallback to GetSystemTimeAsFileTime , it is possible to build modern applications that benefit from the precision of the new function on Windows 8/10/11 while maintaining full compatibility with Windows 7. Ultimately, the decision to support Windows 7 will depend on your application's user base and the ever-evolving landscape of Windows development, but for now, a well-coded fallback ensures that everyone can run your software, regardless of their OS version.
"The update is part of Windows 7 Embedded." Truth: Windows Embedded Standard 7 can also use KB2813345, but it's not pre-installed.
The simplest and most complete solution, however, remains . These modern operating systems support the API natively, providing access to the latest, most secure, and highest-performing applications without any compatibility workarounds. Whether you choose to patch, code around it, or upgrade, understanding this API is key to bridging the gap between modern software and legacy systems. getsystemtimepreciseasfiletime windows 7 upd
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is missing or could not be located in API-MS-WIN-CRT-TIME-L1-1-0.DLL , you are facing a common issue related to outdated system components.
static void InitFunction(void) HMODULE hK32 = GetModuleHandleA("kernel32.dll"); if (hK32) pGetSystemTimePreciseAsFileTime = (GetSystemTimePreciseAsFileTime_t)GetProcAddress(hK32, "GetSystemTimePreciseAsFileTime"); By employing runtime dynamic linking and a robust
Solving GetSystemTimePreciseAsFileTime Errors on Windows 7: Updates and Workarounds
The iperf3 community has addressed this by: The simplest and most complete solution, however, remains
void InitPreciseTime() HMODULE hMod = GetModuleHandleW(L"kernel32.dll"); if (hMod) preciseTimeFunc = (GetPreciseTimePtr)GetProcAddress(hMod, "GetSystemTimePreciseAsFileTime");
PGETSYSTEMTIMEPRECISEASFILETIME pGetSystemTimePreciseAsFileTime = (PGETSYSTEMTIMEPRECISEASFILETIME)GetProcAddress( GetModuleHandle("kernel32.dll"), "GetSystemTimePreciseAsFileTime" );
Are you trying to that won't start, or are you looking to implement this in your own code ?
The lack of native GetSystemTimePreciseAsFileTime in Windows 7 once forced developers into messy workarounds. However, with , Microsoft officially back-ported this essential function, allowing legacy systems to achieve near-microsecond timestamp resolution.
