I did some looking into MUI for the office I'm working for at the moment, looks like you can only get it (and therefore the languages therein) via a Volume License or similar agreement. Once you've got it, though, it's very easy to use. I installed it just yesterday, very easy.
I have a question, though, can anyone think of a way the users we're setting the machines up for could switch from one language to another using a shorter path than the one below?
Start/Settings/Control Panel/Regional and Language Options, click on languages tab, select desired language, logoff and logon again.
Maybe it's just me, but it feels like there ought to be an easier way, especially since Microsoft have a tendency to programme in about half a dozen ways to get to the same place for pretty much everything they make.
Or maybe some fiddling with the registry to get the values made into buttons for the desktop? (My boss' idea. He heard somebody say that they'd once been able to do that and so wants to know if we can replicate it)
Probably we'll end up just using it as is, but it is an interesting question. Anyone got any good answers? The sooner the better, since the deadline for rollout is getting closer.
