In SQL Server you have a choice of default languages for users. Of those choices you have English or British English? So what's that unqualified English referring to then? Presumably Microsoft feel that Microsoft English (yes, they do make up words - "Outdent" anyone in PowerPoint?), or maybe they mean US English is now the definitive version and does not need qualification, whereas British English does. I would beg to differ...
Then of course, as British English users we have to suffer US English spellings throughout the Windows UI (and countless other apps). Color instead of Colour anyone? I know it is a small thing, but surely it is not beyond Microsoft to help my children not get confused over which spelling is correct. After all if I had an French installation I'm sure the spelling of colour would be correct for that language (Couleur).
And recently I learn that .Net does not support Welsh as a culture. I'm not sure how many Welsh speaking citizens there are out there, but I bet it is more than some of the more obscure cultures that are supported.
So come on Microsoft - this can't be a big deal - lets have proper recognition and support for the British English and Welsh languages...
