your account is online,, you can log into your same microsoft account on any computer from anywhere in the world,, its not a local account , windows microsoft account is a hotmail/live account,, its all the same god dam thing.
so if you loose your computer,, you can buy a new one, ,and log in with the same account. da
no different than a cell phone,
computers are not for everyone,, thats the problem i see.
when i worked at Dell , they had to offer to buy computers back from some people as they kept calling with so many problems, ,and the problem was not the computer it was the user, lol
