Hello. I have on my computer windows 8 pro and i wanted to update it to windows 8.1. I burned the iso Windows_8.1_EN-US_x64.ISO and tried to install it. When installing it wants a serial number and my windows 8 genuine serial does not work. Do you know why ? Thank you.
you have to install it with a 8.1 gvlk key then activate with your windows 8 retail key online or phone
Hello and thank you for your answer. @rrohela : When i launch it, it ask me if i want to download important updates or not and then ask for the key !!! @Jessica Alba : Where can i find this key ?
Thank you. I installed with the key of pisthai but i still have 2 problem. I don't find how to install the french language pack fr-fr/lp.cab and i don't find how to insert my genuine key ? Thank you
Open the Settings charm and go to PC Settings. Go to the Activation category. There should be a button to enter a new product key.
