    That would probably mean the key would be upgraded and a unique identifier embedded on the machine? (I don't know)

    I'd rather do it like we did with Windows 8, toss MS a few bucks, get a whole new key and keep your previous OS legit as well.
    I plan on getting the DVD/ISO when it comes out so I have both a key and a way to install my copy on a new PC when I build one. The free upgrade is nice and I'll do that as well.

    (For as long as it's supported anyway)

    I'd spring for a few copies of Windows 10 at 15 bucks a piece! I'd be upgrading any machine I could find!
    That makes two of us!!! A free upgrade is nice, but I would rather keep my licenses for W7 & W8.1 Pro.

    Edwin,
    Would that mean you couldn't go back to Windows 7 or 8 if you didn't like windows 10?

    Not sure. They may have a rollback feature implemented for a certain amount of time.
    I was hoping there was going to be a stable Consumer Preview to try in April but I don't know if that's going to happen either.

    I think that the product key from the existing 7, 8, or 8.1 OS will work for 10. I did a clean install of 8.1 and the 8 key worked. And then I added the media center key and that worked also. Probably as long as it's on the same mobo it won't matter. I did a clean install of 10tp and the iso was for the pro version even though the links were either x64 or x86 . I'm just hoping that there will be a way to make a DVD so I can do a clean install of the public release.

    I'll speculate here a bit,, When Win10 does come out MS will use the existing key(Win7/Win8.1) to validate the PC and then supply a new key for Win10. By doing this the user can keep the old OS and have access to the new one.

    I hope.. not sure if it's going to happen this way but this is all speculation by myself at this time.

    What about pre-activated systems? One pre-activated key is used acrossed several systems. One person could upgrade, another person wouldn't. I suspect those with pre-activated oem keys, will have to use the OEM key on the back or bottom of their computer or it would make some computers still using windows 7 or 8.1 look not genuine.

    Those pre-activated keys are tied up with a unique hardware identifier registered with MS. Although the key is the same, MS will still detect it as a unique key. You shouldn't worry about it. You can rollback and keep your old OS as long as you want.

    The issue with multiple keys across is not really an issue that MS has to deal with, do they?? It should be one key per system and if there is a situation were the same key is used for multiple systems the first one to upgrade wins??

    I think that will be worked out but it's up to the user to make use of the key they were supplied with and hope it's not been used for more than their system.

    That should hold true. And in the end I think MS would want to get rid of multiple key usage.. keep in mind some may be pirated.
