I just upgraded from windows 8 to 10, and have been having issues with cortana. She does recognize my voice, when I say 'Hey Cortana', but anything I ask her, like what is your name, tell me a joke, tell me a story or anyhting like that, she simply opens up Bing search results instead of responding to me. I am logged in to my microsoft account, for logging into my pc. Please help me resolve this issue, I am really thankful.
