If I just bought a laptop with win10 pro can I use downgrade rights to install win7 pro without using one of my retail licences (which I have separately - and can use if required)? Or should I just use my retail licence and not mess with the win10 licence?
The laptop was previously shipped with win7 so all the drivers etc are on the website - along with ubuntu too which I shall also play with if i can get it to dual boot.
is there any penalty to going to win7 in terms of screen scaling (it's 3200x1800 pixels on 13.3 inch screen).
