i just recently upgraded my acer s3-391-6046 that i just bought to windows 10 for free but i am getting this message:

 

Activation Failed Because This Device Doesn’t Have A Valid Digital Entitlement Or Product Key. Error Code: 0x803F7001

 

i already did a reset / clean install with windows and it still says not activated.

 

what should i do?

 

thanks

      download this:

    http://www.nirsoft.net/utils/produkey-x64.zip

    unzip and run the exe, this will recover your windows 8.x product key, now:

    1. Select the Start Start button icon button, then select Settings >Update & security > Activation.

    2. Select Change product key, and then type the 25-character product key.

    ps may see several but use the one from the BIOS.

     

    pps this will not work for Win 10 but should to restore to 8 or 8.1, then follow the upgrade path to 10.

     

    ppps the usual cause of this is an install from a DVD. If you pull Win 10 from the web page it should generate the new Win 10 key and activate.

    Sorry, forgot that method for activating:

    1) run SLUI 04 (note the space)

    2) select your country

    3) Call number indicated

    4) When propted, read the long number at the bottom of the screen

    5) Have pen and paper ready for the activation code.

     

    If that does not work, see my earlier post.
