Ok so microsoft have made it harder to test and clean install, Windows 7 could be installed with no key.
I have found a way to download the 8.1 ISO without a key from here.
My 2 questions are.
1 - Is there a way to put 8.1 to test on my spare rig without activating with one of my retail keys? So basically is there some sort of trial key?
2 - When I decide to put this on my main PC and laptop for proper use, is there a way to clean install 8.1 using a 8.0 upgrade key? I dont want to do a messy upgrade process, my motto is clean install is always better.
I will probably google and find answers anyway but interested in people's experiences.
