  1. OEM Key not Activated


    I downgrade Windows 10 to Windows 7 but OEM Windows 7 Home Premium key by Sony Corporation, enter product key is say Key is invalid. I checked specs page is Windows 7 Home Premium Factory Windows and installed same edition but Windows say I have 3 days to activate Windows, not 30 days to activate. I think I install wrong build. When I installing, Windows 7 is created windows.old Old Windows 10 and still in drive and I have product key Windows 10 linked with Microsoft account so I think there have way to revert and use windows.old.Where I download Windows 7 .iso: Windows 7 SP1 Home Premium

    :)

    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.

    activate windows 7 oem key

    Is there any way to activate a oem key in a win 7 wich has not been installed with the oem disk? The key is the one wich came with the computer and I installed version that matchs with it, so there wouldn't be any problem of using any other disk of win 7, but it doesn't activate.
