    Hello Bob,

    You would just need to select to boot from your 64-bit DVD at boot instead of your 32-bit Windows 8. Afterwards, you should be able to do the rest of the tutorial on the first page to delete the 32-bit Windows 8 and installed the 64-bit.

    So I do not have to worry about making a boot disk/usb, I can just boot/install directly from the dvd's ?

    Nope. The DVD will be bootable.

    That is just wonderful news, thank you

    [EDIT]: And I am back in a 64 bit system, too bad I could not choose to format my system drive during install.

    You're welcome. I'm happy to hear that you are back to 64-bit now.

    If you selected your old 32-bit Windows partition to install to, then it would have formatted it for you during installation. You might also check to see if you may have a Windows.old folder that you could delete to gain back more HDD space since you didn't start the installation with a deleted partition.

    When I bought my Windows 8 Pro Upgrade from a store I was not asked for my qualifying OS key so I suspect this is a flaw in the system which someone clever just found out because there is no instructions from MS of this nature.
    THe very nature of the way this is done is the give away. else it would itself go do a refresh...or is this just MS wanting you to install your 'old' OS each time?
    I also did a clean install to start with and had to install Win 7 again because I did not know this method.
    Anyway thanks Shawn for your very informed and talented mind...I wont tell a soul

    Hey Ray,

    It's mostly on the honor system to abide by the EULA to have a qualify OS when you buy a packaged Windows 8 upgrade in a box from a retail store.

    Normally an upgrade is for upgrading from within the old Windows to the new Windows 8. However, Microsoft just allows it's customers to be able to do a clean install with an upgrade copy so as not to have to reinstall the old OS first and upgrade each time you need to reinstall Windows 8.

    @Brink Refreshing the PC has obvious disadvantages (like removing many of your apps). It really doesnt seem like a Refresh would be necessary to do on an 8 install that's completely fresh and umodified and simply needs to be activated. That is my situation, and I have 2 Win8 Upgrade keys, one that i bought from Microsoft online, and another that i bought at Wal-Mart. Of course, when i attempt to use either of the keys, i get an error code, which i fully expected. However, it just seems like a Refresh isnt the best way to accomplish this, there's got to be a better way. I do also have a 7 Upgrade key that i bought on a student discount a few yrs ago (but lost the piece of paper the key was printed on, as well as the install disc). I found the following method on the Microsoft forums as well:

    windows 8 activation after clean install does not accept product key - Microsoft Community

    1. Run the registry editor (regedit)
    2. Find the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\OOBE
    3. Change the value for 'MediaBootInstall' from 1 to 0
    4. Open an elevated command prompt (run as admin)
    5. Run the following command: slmgr -rearm
    6. Reboot

    Now you can activate.

    Besides those 2 methods, is there any other way to accomplish this?

    Thanks!

    Hello Stephen,

    There's not any other legal means than these that I know of.

    If doing this from a clean install, then a refresh is the easiest and quickest method to activate.

    Other than that, using OPTION THREE in the tutorial below for the same as what you posted above will work in Windows 8 as well without losing anything.

    ...then use this tutorial below to change/enter your legal product key number to activate.
