can confirm that the new build the present day, is 16386? or is what we have been using so far, 16385?
Build number have nothing to do with loaders ... you may have different build number is you installed unofficial "leaked" updates ...
I don't know what the 16416 is. But I think 16386 is just the same as 16385, 16385 is rtm x86 and 19386 is x64. Cause I have both x86 and x64 dutch iso's (checksum is msdn), the x86 is 16919 and the x64 iso is 16920, so it seems that the x64's buildnumber is always 1 higher than the x84 from the same language.
