Hello all, It's very late... but I have a question. Have some Win7 Premium Upgrade disc(s) on order, Debating whether to cancel the upgrade disc(s), or use the other images I have... One question I have on the Win7 Premium Upgrade disc(s) is the process to do a clean install with them on a newHD/machine. (I was wondering if it was like Vista...Install without key, then upgrade over install...) I keep reading conflicting info on the net that: A: A activated MS OS must be on the hd. B: MS is killing the OS license of the OS you use to upgrade from? Can anyone expand on my options? .
