I have win 8.1 and would like to update it to win 10 but I want to format my hdd first, so I can make clean install
Do anyone know if I can do that straight away or do I need to literally update my win 8.1 to win 10 first - so it can confirm my licence first.
I don't want to find out, after making clean install that I need to instal 8.1 again, update to 10 so I can get my old licence and then format my drive and install 10 again
