Upgrade from Windows 8.1 Pro to Windows 10 Pro.
Upgrade from Windows 8.1 Pro to Windows 10 Pro.
I plan to set up Windows 10 Pro on my new machine. It seems installing from scratch is preferable over an upgrade. Can I use my Windows 8.1 Pro activation key to get Windows 10 Pro activated?
It's not.Just upgrade because you know why?It saves everything you had on 8.1 and just changes stuff like layout and adds some stuff.There is no difference between clean install and upgrade The only way you can clean install is by buying a key
This statement is incorrect. You can clean install without purchasing a key.
You have the option to upgrade while leaving nothing behind, followed by a disk cleanup afterward.
