I have a laptop which has windows 10 home on it.
I have a windows 7 ultimate disk which when installed on a PC gave me Windows 10 Pro.

I'm wondering if it's possible to upgrade my laptop to Windows 10 Pro from my windows 7 ultimate disk without a complete new install?

Assuming you haven't already used the license in another system and it's a retail license, open a command prompt and type slui 3 and enter the license key. It should upgrade to pro
