This is such an idiotic clause...
Say you got a copy of Windows 98 with a Compaq Presario 2066 - which was one of the biggest pieces of crap ever - The computer, which wasn't very good to begin with, dies on you, and three years later, while that piece of equipment is long gone and probably melted, you want to do whatever you want with the OS - install it on another machine, sell it, eat it for breakfast... since you've paid for the bundle, who's to say you can't dispose of it as you like?
