Just like Gmail.com is for “Google account”, now we got Outlook.com for a “Microsoft account". The question is what is this unheard “Microsoft account”? It is simply the new name for what used to be called a "Windows Live ID." A combination of an email address and a password that will allow you to sign in to services like Hotmail, Xbox LIVE, Windows Phone, or SkyDrive is what Microsoft account is all about. In case you already have an email address and password from which you use these or other services, this means you already have a Microsoft account (and don’t know) —but you can also sign up for a new one if you like. In due course, all Microsoft services will be given new names.
