I am starting a thread to discuss an as yet untested upgrade scenario. All
of the upgrade scenarios tried to date with Vista in both TechBeta and CPP
have been upgrades to running operating systems, either XP or an earlier
build of Vista. MS has not yet released a beta build that is an upgrade
only build. All of them have been full editions. So I'd like to speculate.
(Note: Upgrading with Vista is different from previous versions of Windows
in that all upgrades to Vista are actually clean installations of Vista. A
traditional, XP style, "clean installation" in Vista is called a "Custom
Installation." The difference is whether or not you are keeping your
programs and files in place or having to reinstall everything.)
What I am talking about here is an upgrade sku. What will Vista Upgrade
editions do?
For those who have forgotten, all retail XP editions can do both a clean
installation or an upgrade. The only difference between the Upgrade and
full editions is that the Upgrade installer checks for a qualifying previous
edition of Windows before proceeding, either installed or on the original
cd. This is what none of the Vista builds we have received to date will do.
All the builds are full editions.
So what upgrade scenarios will be supported?
Using XP as an example, you can do an in place upgrade from Win98 or ME to
XP Home, or Win98, ME, or 2000 to XP Pro by simply inserting the XP cd while
the older OS is running and clicking Install Windows on the splash screen.
However, if you try that with Win95 running you will get the message
"Upgrade is not an Option" when you click on Install Windows. The same will
happen if you try to upgrade from 2000 to XP Home that way.
Does that mean that Win95 does not qualify for moving up to XP by buying the
Upgrade edition? No. It just means you have to do a clean installation of
XP and have a Win95 cd that you can insert when the XP Upgrade Setup
requests proof that you qualify for the upgrade price.
The reason is that Win95 had reached the End Of Support before XP released
and so MS did not test the Win95 to XP upgrade scenario. Win95 was no
longer a supported OS. Since it was untested, Microsoft Product Support
Services could not guarantee users that they could help them through the
upgrade process from Win95 to XP so the option to upgrade in place was
disabled. PSS could only guarantee success if the user was doing a clean
installation. Thus the odd situation where an unsupported OS qualified one
to take advantage of Upgrade pricing but only when doing a clean
installation.
And that brings me to Vista. Win98/ME reached End of Support on July 11 of
this year. MS has no need to test any upgrade scenarios for unsupported
OS's and clearly PSS will not support users trying to do an in place upgrade
to Vista. Upgrade is not an Option will be the message if attempting to
upgrade to Vista via a Win98/ME desktop.
Question of the day: Will a Vista Upgrade edition Setup accept a Win98/ME
cd as a copy of a previous edition of Windows qualifying for the Upgrade
price? Should it still accept a Win95 cd?
My thought: If MS wants to get the remaining installed base of Win98/ME
users off of those systems, it will. (Who cares anymore about Win95 anymore
anyway?)
I imagine that the majority of those moving up from the Win9x/ME editions
will simply get Vista preinstalled on a new computer, but there will be some
Win98/ME users who have adequate hardware for the upgrade.
Remember, none of us has seen a Vista Upgrade edition build.
