Windows 10 key

[Walkerie]

Hi all,

I am currently using the enterprise evaluation version, really happy with Windows 10. If I were to buy a professional key can I use that on the enterprise edition and it'll downgrade me? or will I need a fresh install. I am coming to the end of the trial

Ok thanks, will I be able to take off old stuff after it expires? to transfer to a different hard drive or am I better off doing that before
