    I normally build all my computers, but this time I decided to just go the cheaper way out and get an HP 500-056 with 8 gigs of RAM and a 1 TB HDD, etc. 23" monitor and everything else is from the old build(s).

    I may look at things again tomorrow, but maybe not. Looks like I still have some studying to do.
    It is supposedly a free update. So, here's the solution that worked for me:

    1) Downloaded the ISO and started the setup in Windows
    2) Entered *any* 8.1 key that suited my version (in my case Pro, not Core)
    3) After the update (it took about 25 minutes), I got: not activated
    4) Used slmgr.vbs -ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX to enter my 8.0 key
    5) rebooted and it was activated

    This is a solution for my particular situation. I have a Windows 8 Core key in the BIOS but am using Windows 8 Pro with a legitimate, genuine Dreamspark key. I do not know why the installation behaviour is a such since it is a free update and shouldn't ask for a key.

    Yours is presumably different because you will use the BIOS installed key. Perhaps you could post an update with your solution if you have found one that works.

    So far, I've been unable to get the product key out of my computer. It's supposed to be embedded in the BIOS, but I can't find it.

    I think it's because the official route to that free update for consumers will be through the Windows Store, available when 8.1 is released in October.

    The ISOs issued to MSDN/Technet folk and leaked elsewhere over the web are described as being for testing purposes.

    Run RWeverything (portable version, runs even from USB stick). Button "ACPI", register card "MSDM".

    Upgrades though the store are free and as far as I know won't ask for a product code. I've done two clean installs with the ISO. The ISO wants a Windows 8.1 key to install, it will not accept a Windows 8 key during install. The first post in this thread has 8.1 installation keys you can use. Windows 8.1 RTM (Core, Pro, Enterprise x86, x64) leaked Those keys listed will let you install but they will not activate. On my laptop the ISO wouldn't use the embedded 8 key to install so I just used on of my TechNet 8.1 keys to install and activate. I was in a hurry and didn't feel like mucking around. On my desktop I used one of the leaked install keys to install. Then I just clicked activate Windows and change product key. Then I typed in a Windows 8 key that was previously used on that PC. It was accepted and Windows activated with it. The ISO will let you activate with a Windows 8 key it just won't let you install with one. Not on a clean install anyway. I have no idea why Microsoft did it this way?

    RWeverything got me mine. The script will work too if you haven't added features like going to Pro or adding Media Center. The script I ran just got me my Media Center key, it reads the currently being used key not the embedded key.
