Having tried all presented solutions, I finally have Whispermode working again, I simply logged out of my Nvidia account and back in, then boom, it was back....... *Scratches head
When I open the Nvidia GeForce Experience, the Whisper Mode 2.0 section that has been enabled for the two months  have owned the unit, now says that it is not enabled by the notebook. Everything else is fully ticked and ready. All updates are the latest versions, not just Nvidia ones but all Windows ones also. Has anyone else encountered the same issue and can anyone offer a solution or some insight?
