Getsystemtimepreciseasfiletime Windows 7: Upd

Windows 7 does not natively support this specific API, and there is no official "patch" from Microsoft to add it.

Introduced with Windows 8 and Windows Server 2012, GetSystemTimePreciseAsFileTime was a significant advancement in the Windows time-keeping API. As documented by Microsoft, its primary purpose is to retrieve the current system date and time with the highest possible level of precision, which is less than one microsecond (<1μs). This is a marked improvement over its predecessor, GetSystemTimeAsFileTime , which typically offers only millisecond-level precision.

(or the later rollup KB3125574)

The precision is 1 microsecond, but the accuracy depends on the underlying hardware and system timer resolution. On Windows 7, the function uses the same system time source as other time functions, just with higher granularity.

Recompile using an older MSVC Toolset (e.g., v143 or older), which does not automatically reference this API. Solution B: Find an Older Version of the Application getsystemtimepreciseasfiletime windows 7 upd

Most modern desktop software is built using development environments like Microsoft Visual Studio. Recent updates to compiler runtimes (such as the C++ Universal CRT or MSVC Platform Toolsets like v145) default to using this high-precision function for standard timing processes.

To understand why this issue cannot be fixed with a simple Windows update, you have to look at how Microsoft handles time precision across generations of its operating system. What is GetSystemTimePreciseAsFileTime? Windows 7 does not natively support this specific
