The license is to that one machine only. It's part of the bargain so the license vaporizee with the machine.
This area does upset a few since they thought they were getting a full license to the OS.
Ask for such, but don't spend any money asking since we know the answer.
I bought a dell lapto some 2 years back with which I got an XP license. Now I do not use the Dell anymore, but the Dell XP CD would only install on a Dell computer.
Without reading small print, I am in my right to ask Dell to release the XP license to me so I can use it on another computer to upgrade from win98 ?
