I am giving my PC laptop to my grandkids and I wanted to migrate what was on the laptop to a Parallels Virtual Machine on my Macintosh Pro. This typically ends up the the need to re-activate Windows. It was really great to be able to purchase a Windows 10 Pro license (what was already on the original hardware) for a reasonable price. My Virtual Machine (a total clone of my laptop) is humming on my Mac. I can now erase the Laptop and give it to the grandkids. Thanks guys.
