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)?
