Here's a slight twist to this whole thing...
Originally I bought my Dell with 7 Home Premium, so the license was "embedded" and would auto-activate if I re-install from Dell DVD.
Then, I did an "Anytime Upgrade" to Ultimate (download), and got a separate key for that.
Last time I clean installed 7, I had to first install Home Premium, let it activate, then do Anytime Upgrade and manually enter it's key.
All was fine.
If I go RTM booted under Ultimate key, do I keep the Home premium key? Since I own both.
If not, I'll be giving MS two paid-for keys to get one!
Time will tell........ Maybe I'll ask Gabe! Nah.......
If this does happen, there are a few denizens in these forums who will very likely be called on to continue testing. I would call some names, but I would be sure to miss a whole bunch of them and I don't want to ruffle any feathers. One thing I can be almost certain of is that the MVPs will be called on first.
I have given plenty of Feedback. So I hope that does help.
I have seen talk about the "key" but I have never been asked for it. Doesn't mean it's not available to a particular segment of testers, but it ain't required for me. Also, I'm not thinking a key would be produced for RTM so far in the future.
I would really like to verify both parts of your statement because it would make life a lot simpler for all of us if we know something is a fact and not just rumor.
