Hi, Mark.
The "full retail" and the "upgrade" packages for Win7 Ultimate are identical
EXCEPT that the upgrade disk will look for an already-installed version of
Windows. Once over that hurdle, you can do either a new or an upgrade
installation with either product disk.
As I'm sure you know, you cannot install 64-bit while running a 32-bit
Windows - and vice versa. Hardware differences require that you BOOT from
64-bit media to install Win x64. You can boot into Win x64 or Vista x64 or
Win7 x64, then insert the Win7 x64 DVD and run its Setup.exe. Or you can
boot from the Win7 x64 DVD and let Setup.exe run automatically. Either way,
you will be booted into the 64-bit environment.
But I'm glossing over the OEM aspect because I've never had a computer with
Windows pre-installed. I've upgraded only a few times; I usually prefer to
do a clean install,
RC

My system is currently running:
Windows Vista Ultimate 64-bit
I'd like to move to Windows 7 Ultimate 64-bit.
I'd also like to be able to install Windows 7 Ultimate
from scratch at an unknown time in the future.
I don't have the OEM (Dell) version of Windows XP (32-bit) that was
originally, but I do have the media and keys from the
Vista Upgrade media that was used to upgrade from Windows XP to
Vista Ultimate 64-bit.
Can I do the upgrade with a full Windows 7 Ultimate package?
This is what I want to use:
GLC-00182 Microsoft Windows 7 Ultimate (32- or 64-bit)
This is what would normally be used for the upgrade:
GLC-00184 Microsoft Windows 7 Ultimate (32- or 64-bit)
(Upgrade from XP or Vista),
but Microsoft has assured me that I won't be able to
do the installation to a new disk more than 5 years from
now because the OEM key, etc., from the original Windows XP
will not be supported.
I have to do an Upgrade, not an install from scratch at
this time. I don't feel like buying a GLC-00182 that
won't be able to "activate", or whatever now, and won't
be able to "activate" in the future when I might need to
use it.
(I can spend the US$100 extra for the full version with no
problem, but I don't feel like paying US$280 extra for
a full version that I won't be able to use on off
chance that I need to use.)
