Comments on Windows Vista Business phone-based activationhttps://www.dotnetzone.gr:443/cs/blogs/birbilis/archive/2008/11/07/comments-on-windows-vista-business-phone-based-activation.aspxI recently had to activate Windows Vista Business (Greek version 64-bit) for a client (a medical lab) that didn't have an online connection to the Internet. So I used the phone-based activation option. This is available by selecting at activation options,elCommunityServer 2.1 SP3 (Build: 20423.1)
