    Windows Pro Upgrade Failed, Now OEM Home Edition Key Won't Activate Either


    I have a ASUS laptop which came with Windows 10 Home. Today, I tried to upgrade to Windows Pro. I paid $100 through the Microsoft Store App, but the update failed. After the update failed, I tried to re-try the update, but now under the activation tab, the Windows 10 Enterprise edition is says it is not activated, and there is an error message saying that Windows cannot activate because there is no valid key with an error code 0xC004C003.I've had the computer for nearly 9 months, the key has been valid this entire time, and was valid today when I purchased the upgrade. Only after the upgra

    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.

    Windows 10 Home Upgrade to Pro using OEM Disc and key

    Hi, Andre

    I have the same problem. I have a Windows 10 Pro OEM key and can't enter it directly to force the upgrade.

    I read that even if I follow your suggestion, I won't be able to activate the Win 10 Pro (obtained via your easy upgrade method) with my OEM key.

    Can you confirm that the OEM key will work to activate the Windows 10 Pro obtained via easy upgrade?

    Thanks

    Bruno

    activate windows 7 oem key

    Win7 and Vista. It did not work with XP, OEM and Retail discs were different for XP(and anything pre-XP).

    If it is already installed, you can enter it when you activate.

    Is it saying the key is not valid or is it failing activation? A screen shot of the error it is giving you would help a lot.
