Earlier quoted context omitted.
Yeah, what ever happened to Create account/Register and Log in? Why have two very different options with almost the same label?
Heh, there was a time when Microsoft’s Polish translators (who I’m mildly convinced are robots in disguise) decided “Sign in” should be translated as „Zarejestruj”. Which is what everyone else called the “new account” button. They managed to fix it since then to a much more reasonable and much less confusing „Zaloguj się”.
I think Windows translators are real humans, because quality is much better than whatever Bing Translator spits out (seriously, who thought it was good idea to automatically redirect to Bing-translated MSDN pages), but translated completely without any context. For example, task manager now have RAM "Form factor" translated as "Współczynnik postaci"...
