I recently changed my pc and just put windows 10 home on it. I didnt activate it for some weeks. now i have decided the watermark at the bottom right of my screen and not being able to personalize windows is annoying me. so i purchased windows 10 pro, Problem is when i boot up the windows installation media from my usb it says incompatable that i must upgrade from my desktop via the setup on the installation media. If i do that it will remove all my files and im pretty sure i would need an activated windows 10 home too. Any help would be appreciated.
