: Windows 7 is officially "End of Life." Microsoft focuses on providing these APIs only in newer kernel architectures.

This can lead to system instability, BSODs, or broken Windows Updates.

, which has a resolution of ~15.6ms, the "Precise" version combines system time with the performance counter to achieve sub-microsecond accuracy. Microsoft Learn Potential Solutions getsystemtimepreciseasfiletime windows 7 patched

If you’ve recently tried to run a modern application on Windows 7—whether it’s a high-performance game like RetroArch : Windows 7 is officially "End of Life

// Typedefs for our dynamic function calls typedef void (WINAPI *GetSystemTimePreciseAsFileTimeT)(LPFILETIME); typedef NTSTATUS (NTAPI *NtQuerySystemTimeT)(PLARGE_INTEGER);

On Windows 7, GetSystemTimePreciseAsFileTime does not exist in kernel32.dll . If you call it directly, your application will fail to load. For years, the standard advice was to fall back to GetSystemTimeAsFileTime , which typically only offers 10 to 16-millisecond resolution. Impact on Software

The function GetSystemTimePreciseAsFileTime was introduced in to provide sub-microsecond precision. It does not exist natively in the Windows 7 kernel ( kernel32.dll ).
