Darrel Gorter (MSFT) reported the results of some experiments he did for us
using an Ultimate edition product key. It looks like good news for those
hoping to be able to migrate directly from W2k and XP 32bits to Vista 64bits
at upgrade prices. It goes without saying that your computer must be 64bit
capable.
His findings:
When you boot the machine with a Vista x86 dvd and enter an upgrade edition
product key you will be instructed to restart Setup from the legacy desktop.
You cannot use an UE pk without running the legacy OS.
When you boot the machine with a Vista x64 dvd and enter an upgrade edition
product key you will NOT be required to restart and run from the legacy
desktop. As long as a qualifying legacy Windows is installed you will be
allowed to proceed. This removes a key concern, which was that x64 Setup
cannot run from an x86 desktop. It turns out that it doesn't have to.
Ealier statements turned out to apply only to the x86 dvd but not the x64
dvd.
Conclusion: If you are running 32bit Windows you can install 64bit Vista
using an upgrade edition product key. All you need to do is boot with the
64bit dvd. Those already running XP Pro x64 should have the choice of
booting with the dvd or running from the desktop.
Darrel believes that the x64 dvd is only included in the Vista Ultimate
upgrade edition box and will have to be requested for the other upgrade
editions.
<Rant>There ought to be a way to only have one retail box, period. Surely
the product key is all that varies and given present technology that can be
purchased at point of sale and generated by the salesperson. You get your
media kit and then tell the clerk what edition you want at the checkout
counter. No problems with open boxes if you make a mistake and need an
exchange since one box does all.</Rant>
