Probably the same as windows 8.1. use a placement key then change the key after install...
Yes but the question is will my 7 key be upgraded to a 10 key by simply adding it to a 10 install, or does it have to go through whatever 'process' the in place upgrade to 7 does in order to register the key as a 10 one.
I get the feeling we simply won't know that until its released and someone tries it.
No biggie if not, I'll just install 7 and update it then blat it clean. I'm just lazy
