Hi, I'm not too sure what category this would go under so forgive me if it's in the wrong place. Last night I updated my Acer Aspire V5-571 from Windows 8.1 to Windows 10. I was very eager to use the Cortana feature but after setting everything up the Hey Cortana feature remained silent. I have done a test with the microphone and all seems fine but Cortana will only work if I click the little microphone icon in the search bar. It is set to respond only to my voice. Any help would be much appreciated. Thanks in advance.
