Today someone asked me whether there is anywhere on the internet that customers can find the Vista locale list. Several of us have blogged about custom locales and the ways in which customers might use them, but I wanted to post the full list of built-in Windows locales here so that is is convenient for people to find. The following is the full list of locales that went into the recently available Vista release candidate, along with their LCIDs and string-based identifiers:
