Using Windows 10 free upgrade for Win. 7

Hi, first, let me say I am not the smartest guy when it comes to computers. I am trying to use the free upgrade to Win. 10 on my Win. 7 pc that is here under the tutorial forum. Last night, I started the download for Win.10 installation media,and it went along without a problem, it started the update, and at about 2 hrs. into the update, (86% complete), the power in our community went out!! This am, I started the pc, and it said it was recovering Win.7, or something like that? It did go back to Win.7, and woks fine, however I attempted to install Win.10 installation media again, and it starts Win.10 set up, but it now asks for the product key. I have the product key #, and enter it, but it says it is the wrong product key #, try again. Last night it did not ask for a product key. My question is, is there a way to get the free upgrade without the product key??

Thanks for any assistance,
Jerry

Is your Windows 7 currently activated?

In a Command Prompt with Administrator privileges (run as Administrator) try the command:
slmgr /ato

First I would like to thank you and others for your help and suggestions. You are not going to believe this, but I went to MY PC and the wrong ID/product key# was not the same as my Win. 7 product#, so it had a change ID#, and I entered my Prod. key # and tried installing again, and guess what!! It worked. In fact I am using it now.

I just want to say thanks again for all the help.
