Hey, I've been reading in the Windows 10 forums for quite some time now. As the time limit for the free upgrade approaches, I wanted to upgrade my MSI laptop which has Windows 8.1 OEM installed. Unfortunately that only entitles me to a Windows 10 Home installation. What would be the upgrade path to end up with a Windows 10 Pro installation preferrably without having to reinstall? Upgrade 8.1 Pro, activate it with Daz or similar? My fallback solution would be to clean install 7 Ultimate and go on from there. Thank you!
