Patch checked in.  It was pretty simple, actually.  Rather than
GetVersionEx from kernel32.dll, just call RtlGetVersion from ntdll.dll.
It returns an OSVERSIONINFOEXW structure just as GetVersionExW, but
it's not tweaked according to the executable manifest, so the returned
info reflects the actual OS info.
