It seems to me that the default language input method changes with apps being loaded, supposed I set my default input language to PT and then use MS Word in Chinese, when I close my Win 8.1, the next time I turn on my computer, the default will change to CN instead of PT. Anyone knows how to make Win 8.1 stays with the default input method and not the last apps used? I went to Control Panel/Language and did not find any settings there beside the one that I already did, which was my default input method set to PT.

Thanks for your comment/suggestion
