Vista upgrade invalidates your XP key

If you choose to purchase an upgrade version of Windows Vista to upgrade XP, you will no longer be able to use that version of XP. Either on another system, or as a dual-boot option. The key will be invalidated, preventing activation.

From Vista's EULA found here (PDF) :

13. UPGRADES. To use upgrade software, you must first be licensed for the software that is eligiblefor the upgrade. Upon upgrade, this agreement takes the place of the agreement for the software you upgraded from. After you upgrade, you may no longer use the software you upgraded from.

I want to "upgrade" my 2005 merc to a 2007 merc for half the price. Can I still keep my old merc? STUPID!

What's a merc?

Looks like I will NEVER be upgrading to Windows Vista then. I paid for Windows XP - Full Version! If I upgrade to Vista and decide I do not like it, Microsoft has no right whatsoever to deactivate my XP key, none! What's the matter Bill Gates, aren't you making enough money already? Now you have to screw people over too by forcing people to buy the full version of Vista so they can keep their XP key valid? Shame on you!

What the hell are you talking about? Do you have any concept of what upgrading means? You upgrade a single OS license, not gain an additional one.

hey hey hey!!! if any big trouble? sell your licenses on ebay!! with cd and all... or sell it to your friend/neighbour/girl'boyfriend/pope/bush who ever... what a world are you living on guys?? of course this wold happen.. just remember that the previous versions of windows didn't do de activation thing... wille xp do and of course they'd invalidate the upgraded key!! obvious??

Some of the above comments are just stupid.

Upgrading means you you upgrade a single OS license, not gain an additional one.
If you were still able to use your old copy, it wouldn't be an upgrade, it would be buying a new copy at a discount because you had an old copy.

Ok, I have an old '95 Ford Taurus. It still runs well despite its 200,000 miles on it. I went to the dealer to trade it in the other day for a newer Ford Freestyle, and can you believe it, they wouldn't give me money for my trade in unless I actually gave them the car!!! The nerve of these people, telling me I couldn't trade in (upgrade) my ride unless I gave them the car. Here I thought I could get a great deal on a trade in and still keep my old car.

Is there any true confirmation that the XP key that was being upgraded can not be activated again? The only source is from this blog, and the EULA doesn't say anything about making it so XP can not reactivate.

to all those people that are bashing the people that are complaining...

noone is complaining that they are not getting a second os license... the biggest complaint here is this:

user has xp pro... buys vista upgrade... installs upgrade and MS deactivates xp pro key

3 months down the road... formatting the hard drive would be nice... BUT what do you do ??

Ms has already changed the upgrading process ( you can't just stick in an xp cd to prove you own a legit copy and do a fully installation of Vista)

you would have to reinstall xp activate.. and upgrade to vista again ... anyone see a problem ?? YOU CAN'T FRICKEN activate xp anymore .. because the first time you did it .. ms deactivated the xp key.


unless we are all reading the eula wrong ... the average " i just want a good computer from best buy even though i know nothing about pcs" is going to get screwed..

you are reading the eula wrong because i don't see anything about not being able to validate your xp. Please show me the part of the eula that says that? Please ...

i do, by common sense, think that this process is not viable!
The upgrade license of windows vista must work with the cd by booting (clean install i mean) otherwise i dont see why one should opt for this method.. unless for the big discount of course.
But just that amount of work by install the previous xp and then upgrade to vista... have someone tryed if this is the only method?

edit: by this sentence i understand that one will never touch windows xp cd and license anymore, not even for the clean install - "After you upgrade, you may no longer use the software you upgraded from."

Exactly, me too.... just another reason to skip Vista. Maybe they'll become consumer friendly again if enough people felt the same way.

I would remove XP from my pc, then do a clean install of Windows 2000 and then upgrade to Vista from Win 2000.

From : http://www.microsoft.com/windows/products/...gradepaths.mspx

If you are currently using Windows 2000 Professional or Windows XP Professional x64, you are eligible for an upgrade copy to a corresponding or better edition of Windows Vista, but a clean install is required.

Upgrade copies are not available for versions of Windows earlier than Windows 2000. These earlier versions of Windows require you to install a full copy of Windows Vista.

If the edition of Windows Vista that you choose to install will result in a loss of functionality over your current edition of Windows, you will need to do a clean install, or install Windows Vista to a new partition on your PC.

Another advantage is it would do a clean install from Win 2000.

I thought they only made it so you can do an upgrade install from within XP?

I remember reading that on here somewhere a while back. That Vista wouldn't do an upgrade install from any Pre-XP OS.

I'm not saying it's true, just saying I remember a thread on here that was talking about that.

EDIT: Looks like you edited your post while I was making my post so nevermind

If I ever do get Vista it would be a full version anyway. Not some upgrade version. My upgrade version of XP Home was completely different from my newer full version. When you did an upgrade install of XP you didn't actually get all the features that you would in a full, clean install. Plus a clean install just runs a lot smoother anyway.

Where in that EULA quote does it say it invalidates your key? This news is bogus. It just says you don't have the right to install your upgraded XP on a system while you have the Vista upgrade installed.

Bingo, people are jumping the gun and making claims to things they obviously don't know anything about. I know a few people who formatted their machine after a vista install with activation and went back to XP and their keys work just fine.

Are you even allowed to use the upgrade with a VLK version? Normal consumers are not even allowed to have VLK versions and I can't imagine why a company with a volume license would upgrade to a retail version of Vista. Seems they'd be going with Vista Enterprise.

You don't own the Software. You never did. You buy the license to run the Software. Don't believe me, ask a Lawyer.

Like it's been said, here's the explanation.

You're upgrading from XP to Vista so why should your XP still be active? By upgrading, you've pretty much said that you've moved on. In the event that you don't like Vista, you uninstall it, and go back to XP.

It's so that you can't have regular XP and an upgraded XP->Vista on two separate computers.

I don't know what everyone's so worked up about...when you UPGRADE something, you simply improve on what you already have. Doing this, you change what you already have to the NEXT VERSION. Soooooo.....How could you use BOTH, since the original does not exist anymore. You can, however, downgrade back to XP simply by reinstalling from your XP disk. You don't actually invalidate the XP license, it just changes to a Vista License. Just ONE...you don't get a license with the Vista upgrade, you just change the existing XP license to a Vista license. Nothing to get all bent out of shape over.

This has to be the most asinine thread I have ever read. Why no one has stepped in to inform the readers of the truth is ridiculous. Has anyone EVER upgraded Windows before? I just want to set the record straight for anyone who stumbles in here as I have.

The biggest problem here is the misunderstanding of how the upgrade works. It does not matter if your XP key has been "deactivated". This is because, in order to install an upgrade version of windows: YOU DO NOT HAVE TO INSTALL THE PREVIOUS VERSION FIRST!!! Yes I am yelling at you!!! A VISTA UPGRADE CAN BE INSTALLED ON A CLEAN DRIVE FROM THE VISTA DISK. AS LONG AS YOU HAVE A KEY TO XP, YOU DO NOT NEED TO HAVE XP INSTALLED!!!

Hope that clears up the confusion. You may continue now.
