Is it an upgrade or full install?

by bigtallpaul / December 14, 2008 10:12 AM PST

I just got a new pc with vista on it and I already want vista gone. I have xp pro on all of my other computers and that is the way I like it. I cloned the c: drive from one of my computers (xp) and I want to install it in place of the vista drive. When I boot the pc up xp will of course realize that there were major hardware changes. I know that I will have to buy a license key from MS but the question is will I need a full install key or will an upgrade key work (and be legal)? Just to be clear here, I am NOT trying to pirate software, I just don't want to buy the upgrade only to find out it won't work and then have to buy the full install anyway.

It's a full retail license you would need, and if you don't have a retail copy of XP, you can't simply buy a new license from Microsoft and expect it to work.

More than that though, you should make sure there are actually XP drivers for your hardware. You might well be stuck with Vista like it or not, unless you're willing to give Linux a try.

If your copies, or copy of xp is a retail version you are allowed to put it on up to I think 5 (maybe more) different computers.
If its oem, then you have to buy another copy (full)
ebay is a good place to find the cheapest used oem, you will have to call Microsoft to activate a used copy but it will be no problem...hope that helps

Sorry no, that's incorrect. Retail copies can still only be installed on a single computer at a time, but the license CAN be transferred to another system. OEM licenses are NON-TRANSFERRABLE, or put another way, are LOCKED to the system you first activate it on.

I think you are confusing the number of automated activations you are allowed before having to call in for an activation code. That does NOT mean you are allowed to install multiple concurrent copies on different systems. It states very clearly in the EULA that you are allowed ONE copy on a SINGLE system.

Staples/Business Depot was offering (only one I've seen) various HP Laptops w/ Vista Business included. Also included was a HP "XP downgrade
Disk" which I believe contained drivers for the newer HP Vista hardware
so that the downgrade to XP(s) could be accomplished properly. Happy
