Upgrade/Clean install Windows 8 RTM/GA in the future

    Upgrade/Clean install Windows 8 RTM/GA in the future


    For your information, I bought my Asus laptop last year that came with Windows 7 Pro.

    I'm planning to upgrade to Windows 8 this coming October, however, it seems they require me to provide the windows product key.

    I download a software called: "Key Finder" to find my windows key, and to my surprise, it's different from the one (the sticker) at the bottom of my laptop. Later, I found out that the key(from the Key FInder) was actually an OEM key for all Asus laptops.

    Now, if I want to upgrade to Windows 8 later, should I provide the OEM product key or the product key from the bottom of my laptop?

    One more question, do I have a choice to format my hard disk before installation if I purchase the upgrade version?

    I'm not sure that the answers to your questions are yet available.

    However, if Win8 is like 7, an upgrade copy would normally be launched from an installed OS. (Exception: when you're changing from 32 bit to 64 bit, or 64 to 32.) You need a product key only to the extent that you need a previous OS installed to run the upgrade.

    A Win7 upgrade license permits you to format the disk during installation. However, an upgrade license won't (officially) install on a blank disk, so you might be in trouble of you formatted the disk, and then interrupted the install process. (You'd definitely have trouble if you formatted the disk with a third-party utility, and tried to install Win8 on it with an upgrade copy.)

    Again, this is how it worked with Windows 7. 8 may be different. (One change: Microsoft has stated that it'll be OK to install the release version of 8 over the RP. They didn't officially permit that with the Windows 7 RC and release versions, although it worked just fine.)

    From what I have read, to use the Windows 8 Upgrade disk, you must have a qualifying windows version (XP, Vista, W7 or W8 RP) installed on your system. Once it sees the old OS it will let you format and do a clean install during the upgrade process. You do not need the old OS product key during this process.
