Almost correct. ;-) There are, in fact, CD Keys for Windows 10, in my case I used it for a clean install. However you are absolutely right in that you do need to extract the CD Key for 10 from an existing upgraded install using any one of a handful of recommended key recovery utilities, some of which are mentioned on this forum.From what I understand, the upgrade has to be done over the prior OS or it will not activate. Since there is no license key involved with the install, you cannot activate the install when done to another partition.
The way I would...I am currently running Windows 7 Ultimate from my C: drive, the internal 1tb drive. I want to install my Windows 10 Pro to my 128gb SDD and make it the boot drive.

The way I would recommend you do this is as below:I am currently running Windows 7 Ultimate from my C: drive, the internal 1tb drive. I want to install my Windows 10 Pro to my 128gb SDD and make it the boot drive.
Ok, that's interesting. Didn't know that. What I was saying is that you can install Windows 10 clean using a CD Key, but that key has to be recovered from a previously upgraded system.The Windows 10 keys are the same on both of my systems.... The only "Key" available which has not been purchased is an illegal version where the system is activated using a different activation server.
Don't know what to tell you. I can only state my experience. I was asked a twice for the CD Key, presumably because I selected 'skip' the first time the dialog box came up. My clean install went just fine, and is activated. Interestingly enough, my system BIOS still reflects a Windows 8 install, but everything is running fine here, so if it ain't broke, don't fix it.If you are referring to doing a clean install on the same system which had been previously upgraded, you do not need a key.
