Hello! I have decided to upgrade my PC (Motherboard, RAM, CPU and PSU), and I have decided to get a retail windows 10 license. The problem is I am uncertain of the install/activation progress because my SSD now has OEM windows 10 (upgraded from win7). Can I just replace the components, start up the PC and install straight up the retail version of Win10 with the USB stick that comes with the license box thing(?) or have I missed something? Parts are already on the way.
