What's the best way to do this?
Windows 7 Home -> Windows 7 Pro -> Windows 10 Pro ?
Windows 7 Home -> Windows 8.1 Pro -> Windows 10 Pro ?
Windows 7 Home -> Windows 10 Home -> Windows 10 Pro ?
Windows 7 Home -> Windows 10 Pro
Bearing in mind this will require me to purchase a "Pro" version of windows, would it be best to purchase W10 Pro and then Clean Install?
Also, do only the "Retail" versions provide the "Upgrade" option, i.e. does OEM only allow a Clean Install?
Thanks
