I have a bunch of old Windows XP Home license keys, but I'm not sure which are upgrades, which are for Retail RTM, and which are OEMs. I do have a XP Home RTM ISO I got of off MSDN

Is there a web site or some way I can see where the key came from plus what version of Windows (Home or Professional, x86 or x64) and type (RTM, OEM, Upgrade)?

You could just install the Windows version you want and then plug in license keys until one's accepted... – Kromey May 11 '11 at 22:52
@Kromey But then that means I have to install Windows at least 3 times before I figure them all out. I don't have that much time lying around – TheLQ May 12 '11 at 2:43
@techie007 First one isn't related as I'm talking about release versions, not service packs. Second one is sorta a duplicate, but I'm asking more of a site than anything else – TheLQ May 12 '11 at 2:50
If you are looking for a website specifically, then SU probably isn't the place to ask. From the FAQ: "SU is not about... websites or web services like Facebook, Twitter, and WordPress" – Ƭᴇcʜιᴇ007 May 12 '11 at 15:58

I use Magical Jelly Bean to find out all the product keys I used to install my various versions of Windows; it will describe the type of license key as well. :) Once you have that information (telling you what type of key it was (OEM, Upgrade, etc) you'll be able to look up any information you need to -- although, it sounds like it gives you the exact information you need without the google-fu'ing.

I use Magic JellBean already, its really good. The issue though is that it requires an existing install using the key. That means that I have setup an XP VM for each key and do everything manually, which is what I was trying to avoid in the original question (note since then I've done that) – TheLQ Feb 16 '12 at 18:22
