Well, this is a theoretical question of course. I got this from the installation agreement:
a. The software may cause the operating system software to conduct validation checks of your operating system software from time to time, depending upon your specific operating system.
b.Validation verifies that your computer’s operating system has been activated and is properly licensed. Validation also permits you to use certain features of the operating system software or to obtain additional benefits.
It seems reasonable that they would want to do it. Has anyone tried installing on orbit converted rtm ?
