We are proud to announce the addition of English for the United Kingdom to the list of Windows display languages. We admit that this is something we should have done a long time ago. Windows users in the UK have gotten by with the US English version of Windows, and while we Americans knew this was not their favourite, that is clearly no defence. We believe that this version of Windows will also be widely used in India, Australia, South Africa, New Zealand, the Republic of Ireland and many other places.
We are releasing English for the United Kingdom as a standalone language. Standalone languages contain all the user interface components needed to be independent versions of Windows. Standalone languages can be used by OEMs to image a PC, or can be purchased as boxed software.
The release of English for the United Kingdom is also a trial run for us. Adding a second language under an already existing primary language code—ISO 3166-2 EN—poses some engineering challenges for us (which is why this took us so long to do). We have had to pay attention to the language fallback chain, for instance. If there are no localized resources available at any time, we fall back to secondary choices and then to English. That used to be English US. But, now there’s English UK as well. Which do we fall back to? So far, planning for these scenarios is looking good.
