Hello I bought a Zenbook with Win 8.1 OEM a few weeks ago. My work machine is 8.1 pro. I consider upgrading the ZB to pro and I'm interested to hear what my best option is. Is there a way to keep the 8.1 key and how to best activate the 8.1 pro? Thanks.
Thanks xinso As w 10 is not at a stage I like I prefer to stay with 8.1 which possibly requires a different "upgrade? Many thanks
