A couple years ago I downloaded a pre-activated copy of Vista Ultimate x64 from TPB. I know now that there was some risk in that, but luckily it has run flawlessly. But now I want to add Windows 7 on another drive and activate using a BIOS mod. As I understand it (and please correct me if I'm wrong), to keep Vista working I'll need to uninstall that activator and install a cert that matches the BIOS mod. That's all fine and dandy, except I have no idea what activator Vista is using, and how I might uninstall it. Hoping you guys can help, and thanks in advance.
