Extract qualifying windows 7 product key after W10 clean install
First I apologize for asking something I am sure has been asked many times, but cant find a definitive answer.
Is there a way to Extract the qualifying windows 7 product key after W10 clean install ?
I did a clean install of W10 after a free W10 upgrade installed and activated. But the activation failed and a MS support person asked me for the original W7 qualifying key......I look after many computers and for some reason cant find which key was used for this PC.....So hope there is a way to find it....
I have now restored a backup and W10 is again activated.....so is this key stored anywhere ?
Many thanks
