I was just like you before, I feel confused when it suddenly appeared after Windows update. But when I did some research from internet. I realized it just an app that work alongside Nahimic. The app which was pre-install on my PC long time ago If you dont wanna be bothered by the nahimic companion, just untick in nahimic companion window. But for me i still keep using the companion, with that app we can keep tracking the update about audio driver as well as the Nahimic version
