I pre-ordered Win 7 upgrade for $50. It did not ask for any proof of earlier Windows license, though technically one should have one as that's what an upgrade is, right? As I had a retail copy of Vista Ultimate from work I figured I was safe no matter what. Then at release it was fairly well documented around the web that one was able to perform a clean install from "Upgrade" DVD and that was my experience as well. Not just once but at least four times across three different motherboards. I would have to go through the phone activation after a mobo change which is a little annoying but it always went fine (and I understand the need to protect themselves in this way). However, the last time (about 6 months ago) it did not go fine. It refused to activate even via the phone system and I had to talk to a guy in India. He would not budge on the "fact" that it was not possible to do a full, clean install on a blank HDD with an upgrade DVD and I would have to install Vista first despite my protests that it had worked just fine multiple times in the past. I understand that's what he had to say but I kept at it at least in hopes that I could determine if something had changed with the system/policy. But I essentially got nothing from him (good at his job). So I am posting this because I am about to try again and as such am wondering about others experiences with this. Especially as I am about to install to a new Sandforce 2 SSD and it sure would be great to not have to install freaking Vista first again and save myself the time and the unnecessary writes to my new drive.
