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.
In 2012, Microsoft released a patch for Windows 7 that introduced a new function, GetSystemTimePreciseAsFileTime , which provides high-precision timing. This patch was initially intended to address issues with timer inaccuracies in Windows 7, particularly in scenarios where high-frequency trading, scientific simulations, or other applications requiring precise timing were involved. getsystemtimepreciseasfiletime windows 7 patched
