There are three methods to which you can activate your product: Online via the internet, by telephone using our automated systems, and by a live support advocate.
Online: When you begin activation, Windows will try to use your internet connection to activate online. If you have problems activating online or don't have an internet connection, you can activate by phone.Follow the “Activate using an Internet Connection” method below to attempt via the internet.
Automated System & Live Support Advocate: To get the telephone number for activation support, follow the “Activate by Phone” method below. You will get the option to activate your device over the phone.
