[rullll1]

is it still possible ? becuase i have just downloaded and installed a windows 10 and my unused windows 8.1 key isnt working.
i based it would work according to this article: http://www.howtogeek.com/266072/you-can-still-get-windows-10-for-free-with-a-windows-7-8-or-8.1-key/

It is not possible. If you download windows 8 from online and then upgrade to windows 10, it should work that way
