    MS hasn't really said anything official about that topic, as far as I know. But I suspect that when you do upgrade you should get a new key for Win10 and the other key you turn in will be deactivated some how. Again.. total speculation on my part.

    It wouldn't make sense for MS to allow that but returning to W7 or 8.1 is possible even now.

    I figured as much. Really just thinking of a really bad worst-case scenario where the upgrade went horribly wrong and you were faced with clean install of previous version, or nothing. Wonder what the fallback would be for that!

    I am happy with Windows 10 Pro on my laptop and it is almost time to do my annual spring cleaning on my main computer, a clean install. Should I install 10 now rather than wasting a lot of time installing 8.1? I think I already know the answer, backup and do it, just want some confirmation that Microsoft won't force me to do another clean install when Windows 10 is released.

    I'm afraid that even MS didn't come out clean on weather even RC or RTM will be available to upgrade to from TP so it's stil a case of "damned if you do and damned if you don't". I, myself, keep one of each in dual boot on separate disks. One of this days MS will decide for me.

    Thanks, that is about what I thought too. I decided to clone my current system to a removable hard drive and then "upgrade" to Windows 10. I will wait for the clean install until Windows 10 is released. I want to avoid being damned to do a clean install twice.

    Just finished the upgrade and it went pretty smooth. I like how the installer checked my system and told me I had nothing to worry about. First thing I needed to do was get a beta Windows 10 driver from Nvidia. A few other minor things I needed to do, but was sure a Hell of a lot faster than a clean install.
