Whatever; French != Japanese. Indeed, they in some sense represent
opposite ends of the spectrum -- Japanese are notably enthusiastic about
adopting foreign words in a very ad-hoc way, whereas French are famous
for being, um, anti-non-French.
I suspect that Microsoft actually did think about this issue BTW; e.g.,
the error messages &c on Japanese Windows are not unnaturally full of
transliterated English words. Probably this process was not perfect,
especially in the beginning, and early computer adopters probably had a
much broader knowledge of English than the average person, but by now a
precedent has been established -- computer users are _used_ to these
terms, and would probably be more confused if they changed.
