If you are a developer trying to keep your software alive on Windows 7, there is no official "update" or "KB article" that adds this function to the old OS. Microsoft intentionally moved newer toolsets (like MSVC v145) to depend on these modern APIs, effectively ending support for Windows 7 targets. To solve this, developers often use a : GetSystemTimePreciseAsFileTime error on Windows 7 #101 To solve this
You need (or later cumulative updates) to enable it. Without this update, GetSystemTimePreciseAsFileTime is not present in kernel32.dll , and your code will fail at runtime.
