Getsystemtimepreciseasfiletime Windows 7 Patched [upd] Jun 2026

Since there is no official Microsoft "patch" to add this function to Windows 7, users typically rely on the following methods:

Instead of directly calling GetSystemTimePreciseAsFileTime , use GetProcAddress to check for the function's existence, and fall back to GetSystemTimeAsFileTime if it's not found:

Understanding why this error happens, how toolchains cause it, and how to patch your system or application helps resolve it effectively. Why the Error Occurs getsystemtimepreciseasfiletime windows 7 patched

GetSystemTimePreciseAsFileTime uses modern hardware timers (like HPET or invariant TSC) that the Win7 kernel doesn't expose through this specific API. 🔧 Workarounds and Solutions 1. Dynamic Linking (The "Best Practice")

However, the open-source ecosystem has largely accepted the patched version as a necessary evil. Projects like , Redis for Windows , and HAProxy Windows have all included similar time-getting fallbacks to maintain backward compatibility. Since there is no official Microsoft "patch" to

Result: Time appears to jump backward or forward incorrectly.

Because many modern applications are built using newer toolchains—such as —they may automatically include dependencies on this function, even if the developer did not explicitly call it. When these applications run on Windows 7, they fail with the error: "The procedure entry point GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll" . Common "Fixes" and Workarounds Because many modern applications are built using newer

On Windows 7, GetSystemTimePreciseAsFileTime does not exist in kernel32.dll . If you call it directly, your application will fail to load. For years, the standard advice was to fall back to GetSystemTimeAsFileTime , which typically only offers 10 to 16-millisecond resolution.

It retrieves the current system date and time with the highest possible precision (sub-microsecond).

: Rather than building with the newest v145 toolset, navigate to your project properties and downgrade the target Platform Toolset to v143 or earlier. This eliminates the implicit link-time dependency on high-precision APIs.

In a stock Windows 7 environment, developers seeking high-precision UTC time were forced to implement a manual combination technique:
