What is GetSystemTimePreciseAsFileTime?
GetSystemTimePreciseAsFileTime is a kernel32.dll function that retrieves the current system date and time with the highest possible resolution (<1 microsecond). Unlike its predecessor, it is not affected by the system's timer interval (the "clock tick"), making it ideal for sub-millisecond timing. getsystemtimepreciseasfiletime windows 7 upd

Understanding GetSystemTimePreciseAsFileTime on Windows 7: Update Requirements and Workarounds
If you are a Windows systems programmer working with high-resolution timestamps, you have likely encountered the GetSystemTimePreciseAsFileTime function. Introduced with Windows 8 and Windows Server 2012, this API provides microsecond precision (actually 1 microsecond steps, though not necessarily microsecond accuracy), solving the millisecond granularity limitation of its predecessor, GetSystemTimeAsFileTime. Once upon a time, in the world of
Once upon a time, in the world of Windows development, there was a specialized function called GetSystemTimePreciseAsFileTime. It was a hero for developers who needed time measurements with microsecond precision (<1us), far better than the standard 1–15 millisecond resolution of older methods.
