I have 2 laptops with Vista Home Premium editions. I bought the upgrade license from MS, to upgrade one of my laptops. I have upgraded one of the laptops fine. Now the question is, If I want to upgrade the second laptop but uninstall the windows 7 on the first one, would this be possible. I am only wanting to swap the OS onto the other laptop as the other one is faster. Is this possible? and if so how can it be done?
