I got a Win 7 Beta key when they were released to the public awhile back, but would now like to install the 64-bit version on a new hard drive to try it out as my primary OS for a bit. Is there anywhere to get a copy? I know I downloaded it when it was released, but I must have deleted the ISO since. While I have no moral issues with getting it off the torrents I do worry about legal issues. Is that something I should be wary of with the Beta?
