By the way, people. None of this is reason to avoid a Windows 7 Upgrade package. It's just a different workaround to the one we had last time.
With Vista we bunged a 'trial' install in place to qualify the upgrade install key.
With Windows 7 we'll just need to keep a partition clone of an activated install, and bung that on the drive first.
Then it *is* different than how it is with XP>Vista and in your previous post you claimed it isn't. Make up your mind. And I have already seen and posted that workaround here anyway. Having to keep an activated partition clone is going to piss off a lot of people. Upgrade disk is supposed to be able to install on any PC at any time without having to jump through hoops. Having to keep an activated image file of the previous OS isn't exactly user friendly now, is it?
