Is this a rhetorical question or do you expect someone from Microsoft to reply? :)
haha, really funny lol. Do you share my irritation? I can understand the requirement to enter the password/key twice if we're e.g. the administrator who's establishing it. In that case, we want to be sure we've entered what we think we've entered.
In this case, though, we're NOT establishing the key. We're merely supplying it, in order to access the system. Shouldn't one entry be enough? I get into this discussion with my brother in law every time I see him, and now he just tells me to "let it go."
