Advantage and you’ve got it right! Linux shall continue to
work and upgrade without bothering to know the origin of the

servers to verify the serial number of the product. If the servers
go down, as it did last year, Vista users worldwide are locked out
of their computers running legitimate copies of Windows Vista."
