Getsystemtimepreciseasfiletime Windows 7 Patched Jun 2026

If you are writing or recompiling code, you can "patch" the lack of this function by implementing a to the older GetSystemTimeAsFileTime .

Instead of rewriting system DLL files, you can place local redirection proxies directly into the application folder.

GetSystemTimePreciseAsFileTime (defined in sysinfoapi.h ) retrieves the current system date and time in a single FILETIME structure (a 64-bit value counting 100-nanosecond intervals since January 1, 1601 UTC). The “Precise” in its name is the kicker: it returns the most accurate system time-of-day available, often incorporating the high-resolution performance counter to interpolate between system clock ticks.

The GetSystemTimePreciseAsFileTime function, introduced in Windows 7 SP1 and later patched for Windows 7, returns the system time in 100-nanosecond intervals, with a much higher degree of precision than traditional functions. This function utilizes the Windows Time Service (W32Time) and the system's underlying hardware capabilities, such as the CPU's timestamp counter (TSC) or the High-Precision Event Timer (HPET), to provide precise timing. If you are writing or recompiling code, you

The error occurs because this specific API was introduced in Windows 8 . Windows 7, even when fully patched, does not natively support this function in its kernel32.dll . Why This Happens The “Precise” in its name is the kicker:
