    Why can't I find my windows activation key?


    I am in the process of upgrading my computer hardware. On my old set up I had an OEM DM copy of Windows so I knew that was non transferrable to a new system. I saw that i could purchase the upgrade to windows 10/11 pro that would make it so my license was retail according to the microsoft store. Upon purchase I did not receive a product key and largely saw that when I sign in it should follow me and activate. I swapped out a bunch of pc parts and was asked to activate Windows. I don't have a product code, and so can't do it that way. I logged into my windows account, and it didn't change anyth

    activate windows 7 oem key

    There is no difference between the OEM disc and the Retail disc with Windows 7. A retail disc will accept a OEM or Retail key, and vise versa.

    If the OEM Key wasn't going to work with the disc you have, it would have stopped you during the install when it first asked you for the key, not during activation.

    What is likely the problem is that, since the OEM version has already been activated once, it is failing activation again. Activate it over the phone using the option given to you on the failed activation screen, and you shouldn't have a problem activating it.

    Why can't I find my windows activation key?

    Windows 8.1 pro + WMC key activation

    This worked for me last time with a Win 8 key.

    Install Windows 8.1 and enter KMS key during setup. Once in windows change product key to my Windows 8 key. Go to add features and enter my WMC add-on key. Drink a beer to a job well done.
