RTM (Release to Manufacturing)
"RTM" and "Final" are tossed round interchangeably...... They refer to the same thing (keep reading). One would not upgrade from RTM to Final or anything else for that matter. When the final builds are voted on and approved, probably 7300, they will be what is available in the stores and on TechNet, etc. and will be referred to as RTM or Final. The issue will be whether you can upgrade any of the RC's or Beta's to RTM, likely Build 7300. I content where there is a will their is a way. The main issue is why? Any upgrade (other than upgrading to itself to avoid having to buy the "Full Version") leaves stuff around from the previous build. A clean install is the way to go since that will...
