For everyone concerned about buying the upgrade disk

[Zidane24]

So I have been reading these posts and the upgrade method is becoming very appealing....so I have a question and a comment. To me the only said benefit of getting the full license is to save time (if you do the double 7 install) unless someone knows something I don't know. Does anyone know that is doing the double 7 install may affect disk space?

No, it won't take any more space. Just a bit more time to do the double install.

You can do a single clean install with the upgrade disc and the keys are retail so your not really gaining anything with Retail over Upgrade other than the upgrade requires a few extra steps during installation, though I doubt it would add up to more that a couple of extra minutes for the install.

It is really interesting and kind of disturbing about this whole Upgrade situation....You can get a real cheap upgrade right now (59.99 for my HP) and use it like a retail license without it being illegal to the license (the OP said that they actually recommend it that way)...to me it is a rip that they even price those retails so expensively considering the only difference I can see here is a factor of time

The FUD Continues

This post says the double install, and simply inserting a "real" XP or Vista disk, is balderdash...

I ordered the 7 upgrade, so I'll find out one way or another. But if 7 does "require" seeing an installed "activated" Windows OS on the target machine, I'm screwed. I built this machine just for 7. No other OS has been on it.

I think you will find you don't have any trouble.

MS wants to get as many people onto 7 as fast as they can . They will make it easy.

Honestly the upgrade disk will allow you to CLEAN install. when ask CUSTOM, select CLEAN install when ask DO NOT ENTER A KEY(read the popup carefully). since your KEY will be a UPGRADE KEY. continue and Win7 will have 30 days.
any time during or instantly after final install. while booting to Win7, open the DVD Device click setup - when ask click "upgrade" when ask insert the "upgrade key" then finish.

The manual should tell you the same thing. only written differently.
I have upgrade disk since Win3. and never have had a problem with CLEAN installs using them.

Double install does NOTHING TO SPACE.

No matter what that post says, I called MS to confirm what I was saying.. What I wrote in my OP is legit. And vista allowed double install, and other windows os's allowed inserting previous OS disks to validate upgrades on clean hard drives

I ordered the Home Premium Upgrade from Amazon, but what would like to know is this ... I am currently using build 7260, will I need to do the double install method, or is going from a RC build to the retail considered a true "upgrade"? Any clarification would help!!!

Well some people are saying that upgrading from RC to the real release is possible, while other people are saying its not. We probably won't know for sure until MS says something about it, or until you try it for yourself. I wish I had a definitive answer for you on this one. Maybe someone else can shed some light on any info they gotten. Double install is sure to work, but your question leads me to believe youd rather upgrade from the RC you have right now. There have been some places that lead us to believe it will be possible, but we prolly won't know for sure until either you try it for yourself when you get your disk or MS says something about it.

MS has said something about it in their engineering blog. Engineering Windows 7 : Delivering a quality upgrade experience

In that link, they give a method for doing an upgrade install from a RC to the RTM. I used it to go from 7232 to 7264 (which was more like an RTM in that it didn't use the beta/RC keys) and it worked. But that was ultimate to ultimate. Anything else might not work.
