    Need to re-install Win8 but only have a WMC upgrade key..

    I had a media center upgrade key for some time which I got for free. Recently I decided to activate it so I could watch digital TV on my PC. However, I noticed that this key is now is now the new product key for my machine and the original seems to be gone forever.
    Can I re-install and activate Windows 8 using the media center upgrade key if I need to, cause it's the only key I've got now?
    If this isn't possible, can someone recommend some kind of disk imaging backup software that will preserve my activated copy so that I'll not have to install from disk/usb again. Thanks.

    Hello Nalydyenlo, and welcome to Eight Forums.

    If this is an OEM PC that came with Windows 8 preinstalled, then the W8 product key is embedded in the UEFI firmware and will automatically be detected and entered whenever you install the same edition of Windows 8 on that PC.

    A WMC key will not activate W8. A WMC key is only good to add WMC to W8.

    If you like Macrium Reflect Free is a good option to create a system image with.

    My machine came with Vista so there's obviously no Win 8 key stored anywhere on my PC. Looks like system imaging is the way to go for a back up in case there's a need for future re-installs. Looking into Macrium now, thanks.

    Your product key will be on your Windows 8 order confirmation email like below. This email is your receipt and COA.
