How should I go about doing that? I have this Dell that came preloaded with vista, and I then upgraded to have windows 7 on it. I am about to build a new PC and would like to skip the process of rebuying Windows 7 is it possible to move Windows over to my new machine and take it off the old one? I thought I read somewhere on here that Windows is tied to your mobo and that you have to call them and have it reset before you can do that but honestly I have no idea. Every computer i have ever had has always had the os preinstalled and though I know how to install an os and reformat I have never had to install from scratch.
