I'm running W10 with latest RTM build (1511). There are 3 new Skype apps (Skype for Video, Messaging, and Phone. They or one of them are sucking 20 to 40% of my CPU (Core M). I can't find a setting to keep the apps from booting with Windows. If I kill the task, it starts up again in seconds. Thoughts on how to solve besides un-installing?
