    Can i activate Windows 10 using OEM Key without fresh install?


    So I just installed windows 10 pro without product key.

    now I want to activate it using OEM key (cause it cost less).

    can I activate windows without a fresh install?

    Also is it safe to activate windows using OEM key (like from eBay)?

    :)

    oem activation key

    I have a window 10 os oem version. I want to do a fresh reinstall on my computer. Can I use the same activation key ( i used in the first place to get my pc up and running) if it has been used before.

    Note: I will use the same cd and the key

    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.

    Can i activate Windows 10 using OEM Key without fresh install?

    Guide: use Pre-activated Windows 7 OEM License on fresh installation

    U can't use this method to "upgrade" ur Windows Home Premium to Pro or Ultimate it simply just backup ur activation key.
