Getsystemtimepreciseasfiletime Windows 7 Patched New! -

Because Windows 7 is out of its support lifecycle, Microsoft does not provide patches to backport this specific function. 3. Is there a "Patched" Windows 7 Version?

"GetSystemTimeAsFileTime() is not precise and can make the wall clock timer jump back up to ~15ms depending on the last hardware timer interruption, that breaks the monotonic time flow." — Chromium Commit Comment

// Typedefs for our dynamic function calls typedef void (WINAPI *GetSystemTimePreciseAsFileTimeT)(LPFILETIME); typedef NTSTATUS (NTAPI *NtQuerySystemTimeT)(PLARGE_INTEGER);

This is exactly how GetSystemTimePreciseAsFileTime works in Windows 8; Microsoft simply exposed this internal calculation via a public API. By calling NtQuerySystemTime on Windows 7, you are essentially back-porting getsystemtimepreciseasfiletime windows 7 patched

If you are running a specific software (like a game, simulator, or lsp-server), you may need to update or downgrade that application.

In some cases, community-created compatibility wrappers (like specific api-ms-win dll sets) might help, but they are unreliable for GetSystemTimePreciseAsFileTime . B. For Developers

The application no longer has a static import for GetSystemTimePreciseAsFileTime . Instead, the Windows loader only needs to resolve GetProcAddress and GetModuleHandleA —functions that exist in all Windows versions back to Windows 2000. The attempt to retrieve the function address will simply return NULL on Windows 7, triggering the fallback path. Because Windows 7 is out of its support

Calling GetSystemTimeAsFileTime to get the base wall-clock time.

Microsoft has never officially supported GetSystemTimePreciseAsFileTime on Windows 7. In MSDN documentation, the "Requirements" section clearly states: .

When a developer compiles an application that to this function, the compiler generates an import entry in the executable's PE (Portable Executable) header. When that executable runs on Windows 7, the operating system's loader attempts to resolve the import address—and fails. The result is the familiar error dialog: "GetSystemTimeAsFileTime() is not precise and can make the

Solving the "GetSystemTimePreciseAsFileTime" Error on Windows 7: Patched Solutions and Workarounds

Without periodic re-synchronization, the patched version can drift. Consider this scenario:

: Use GetModuleHandle and GetProcAddress to check for the function dynamically at runtime instead of hard-linking it, as seen in this C++ safety block:
