No, I replaced it with splitting the OS version string. In any case, would that cover, e.g., the hypothetical cases Windows 27, Windows Server 2038, etc.?

Unfortunately Miscrosoft does not provide a reliable API to obtain the build number. `GetVersionEx` is deprecated. [KUSER_SHARED_DATA](https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/ntddk/ns-ntddk-kuser_shared_data) contains `NtBuildNumber` but some device driver kit has to be installed to use it.
