Microsoft has been gradually making it harder to activate Windows (and other products) without an internet connection. Most recently, it started clamping down on local accounts that could bypass OOBE sign-in, and now we're seeing reports that another legacy method has been retired. Phone activation, where you could call Microsoft to activate Windows & Office, no longer works, as Ben Kleinberg demonstrates in a new YouTube video.
Now, it'd be reasonable to assume that something as archaic as calling to activate your license had probably been sunset long ago. However, you'll be surprised to learn that Microsoft still lists it as a viable method in its support docs. This is particularly important for people on older operating systems like Windows 7, who expect an offline alternative to Microsoft’s now-online-only activation systems.
