Are you trying to that’s giving you this error, or are you developing an app and looking for a way to support Windows 7? GetSystemTimePreciseAsFileTime error on Windows 7 #101 getsystemtimepreciseasfiletime windows 7 upd
Backporting this functionality required changes to kernel32.dll, ntdll.dll, and the kernel itself. KB2813345 provided a limited, but functional, backport.
If an application or game refuses to launch due to this error, you can circumvent the issue using the technical workarounds and alternative patches outlined below. Understanding the Root Cause
typedef void (WINAPI *GetPreciseTimePtr)(LPFILETIME); GetPreciseTimePtr preciseTimeFunc = nullptr; Without KB2813345, these applications on Windows 7 suffer
GetSystemTimePreciseAsFileTime is a Windows API that returns the current system time with high precision. It was introduced in Windows 8 / Windows Server 2012 and is not available on stock Windows 7. Below are practical options and code patterns to achieve high-resolution time on Windows 7 and how to handle calls safely if you must run on multiple Windows versions.
Linking and manifest
(or the later rollup KB3125574)
This feature attempts to load the Windows 8+ API dynamically. If it fails (indicating Windows 7), it calculates the time by combining the steady performance counter with the system wall clock.
: Download the latest release from the VxKex GitHub Repository. Install the package, right-click the problematic application's .exe file, select Properties , navigate to the VxKex tab, and check the box to enable extensions for that specific program. 2. Downgrade to a Windows 7-Compatible Version
