    I installed Win 8.1 Update 1 as a clean install from my bootable USB Thumb Drive. I entered the bogus serial to do the initial install. I then used several programs to retrieve the legal serial from the BIOS as this came with Win 8 as it is a Compaq Laptop with 8 preinstalled. It only shows the serial I installed with and not the real one I want as it is the legal one. Sure I activated it with KMS thing but if I have a legal serial then why not use it. I have done this previously with Win 8 and it gave you the real serial from BIOS. How do I get the legal serial from BIOS now with 8.1? Thanks.

    If you didn't used the exact same Windows 8.1 as your key is licensed for, you could not activate Windows 8.1 with that old Windows 8 Key! To get the key from BIOS, use THIS and that should do the job. Or, you could use the MKT 2.51, downloaded from this forum for to activate the new version!

    Huh, activated Windows 8.1 Update 1 with Windows 8 OEM: DM keys on 2 notebooks, which have been shipped with Windows 8 (Core). As it was first start both activated automatically on first net contact.

    Or what you're trying to tell?

    Windows 8 Core to Windows 8.1 Core
    Windows 8 Single Language to Windows 8.1 Single Language
    etc., etc.!



    And WHERE the OP was mention WHICH Windows 8 were installed? I didn't see that in his post, did YOU?! And WHERE he also mentioned more than ONE Laptop?

    Please enlighten me!

    Calm down, no offense involved :g:. Only referred to your slighly diffuse post and gave an example of two working installs.

    Ok this is 1 laptop. It came with Windows 8 Core. I just now cleaned installed Windows 8.1 Core. To install I used the bogus serial that we know thats out there just to get Windows installed. Then you just change the serial to the one that is in the BIOS. I used many programs that have worked for me before but for this install they only give me the key I used to install and not the BIOS OEM Legal key. I hope I have explained better this time.

    Try to uninstall the key:

    Code:
    cscript slmgr.vbs /upk
    Then check again.

    Thanks for all your replies. What worked was the pkeyui.exe program. It pulled the key out of the BIOS. You folks are great. Thanks.
