How can I activate my laptop?
HI Microsoft Experts, I have just tried to login in into my microsoft account on the laptop. The messages comes: "Your device is deactivated, go to the admin." I am the admin and do not know how to activate it. So my question: How can this be activated? I am happy for every answer nice regards Sebastian
