    Note   Note
    Note that although you may previously purchase a legit Windows 8 product key, the product key is unlikely able to be used to install or upgrade to Windows 8.1. Hence you will need the following product key to initiate the install or upgrade:


    Windows 8 (core): 334NH-RXG76-64THK-C7CKG-D3VPT

    Windows 8 Pro: XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB

    Windows 8 Enterprise: MNDGV-M6PKV-DV4DR-CYY8X-2YRXH
    FHQNR-XYXYC-8PMHT-TV4PH-DRQ3H

    KMS setup keys (8/8.1): Appendix A: KMS Client Setup Keys


    The keys above will let you install 8.1, but that's all it does. After installation is complete, you will still have to activate with your own Windows 8 key.

    Since I actually have two Win8 Pro product keys (one for the initial install, the second for the WMC add-on), should I only use the first to activate?

    Will I then be able to use the Win8 Pro WMC add-on key to add WMC to 8.1?

    Folks,

    This is all great, but how do I tell my freshly installed Windows 8.1 to use the BIOS-baked OEM Windows 8 key on my Surface Pro? Do I use the SLP key for Windows 8 Pro?

    FYI, my Surface Pro was upgraded to Windows 8.1 Preview, which trashed my ability to use my Windows 8 recovery partition and use it to do a "Reset" of Windows. Hence the reason to install from the ISO, which forced me to use one of my TechNet Windows 8.1 keys.
