Getsystemtimepreciseasfiletime Windows 7 Patched

The function GetSystemTimePreciseAsFileTime was introduced in Windows 8 to provide sub-microsecond precision. It does not exist natively in the Windows 7 kernel (kernel32.dll).

, have implemented patches in their source code to detect the OS at runtime. If they detect Windows 7, they dynamically load GetSystemTimeAsFileTime instead, preventing the crash. Toolset Downgrading Official guidance for developers who support Windows 7 is to use older toolsets (like getsystemtimepreciseasfiletime windows 7 patched
