Does Vista upgrade invalidates the XP Key?

[PSiegmann]

Hello newsgroup.

Here I got Vista Home Premium Upgrade, and want to install it.

I have XP Professional, So I need to do an clean-install. Following
question: I read that Vista Upgrade invalidates your XP Key:
http://www.neowin.net/index.php?act=view&id=37676

Is that a stupid rumour, is that indeed the case? And, does it do that
even when using the clean-install option? (i.e.: you have Vista Home
premium upgrade, but your installed XP is professional) If yes, how
does it even work? Is it sending the xp key to MS after install, to
blackmail it?

You would need to return your "upgrade version" of Windows
Vista Premium and purchase a "full version" of Windows Vista
Home Premium if you wish to perform a "clean install".

Not true. If you have Windows 2000 or XP Professional, you need to do
an clean-install, but you can still use VHP Upgrade.

As it seems, it does a clean-install, but checks if you have xp or
win2000 installed on the HD, if not, it won't install.

I just ask, how the "invalidation" works, (if it does at all), and how
does it work when using clean-install-upgrade.

The Windows XP license becomes incorporated in the
Windows Vista upgrade license which then completes
a fully licensed product. Thus, the Windows XP license
cannot be used again if you want to install Windows XP
separately without Vista.

Gotta agree with Carey here, when you UPGRADE, you get the operating system
for less because you're using an existing Key and turning it into a new
product.

If I got an upgrade version of Vista and was still able to use my Windows
XP, that's like having 2 OSs instead of an upgrade of an existing OS.

Only reason you MAY of been able to upgrade from Windows 2000 to XP and
still use Windows 2000 (even though you weren't supposed to) was because
Windows 2000 doesn't have that online activation stuff.

Read the EULA, i'm sure it's all in there... somewhere.

You may be able to "fool" Windows Vista Upgrade into installing without
validating that you already own Windows XP, but from a legal standpoint...
well yer on your own.

It's the honor system (and something tells me it wasn't be design).

If you use the Upgrade disk to perform a clean install, you *could*
still use the old XP key on another PC, but it would be in violation of
the EULA.

Is that what you meant, or were you asking is it possible to revert from
Vista to XP on the same PC? If so, then this is fine.
