How does this work? Does it just set the synced language and keyboard settings if they are available, or does it actually install them? Because I can sort of see the point of the latter. If I somehow end up in, I don't know, Korea, and find a Windows 8 PC, it'd be pretty neat if I could switch between English and Dutch input languages without having to configure them first.
Keyboard settings seems less usefull, although I've made my own set of keyboard settings once, and would be blown away if that magicllly became available on this hypothetical Korean PC as soon as I had logged in.
